Error! Invalid payment amount!

Hi @sagithereal,

I’m afraid I’m not able to find a form when I check the mentioned page. Possible to share the form export, so that we could test the form on our side and see what might be causing it?

Please check the following doc on how to export a form:
https://wpmudev.com/docs/wpmu-dev-plugins/forminator/#import-export

You can share the export file via Google Drive, Dropbox or via any such cloud services in the following reply.

We are looking forward to your response.

Kind Regards,
Nithin

Sure, here is the export: https://drive.google.com/file/d/1nu8LhatftCdKs8hEpOEB7TTplnI4Z58D/view?usp=sharing

Hi @sagithereal

Thank you for the form.

I tested it on my lab site but it worked without any issue.

On PayPal are you testing the Sandbox account: https://monosnap.com/file/OP7GrSuUN6eoKm4pVfn9mM0HoWY0RV

If so, can you double check your PayPal Keys?

Well. I checked everything once again. I also created my sandbox and live apps once again and also tested both methods, paypal login and credit card. It still gives me the “Error! Invalid payment amount!”. I also got the confirmation from your testing website about my form where there was info about “Price: 0” and You used fixed value “5”. I don’t really know if it does matter in any way.

In summary, first of all I disconnected paypal at all, created new sandbox accounts and app, then connected it to forminator. Next i created brand new live app and connected it. Next i simply opened up the form and it doesn’t matter what input do i give to it, its still returning me the error.

I feel helpless..

update:
after changing paypal from sandbox to live, everything works fine tho. This doesnt change the fact that sandbox doesnt work and i would highly prefer to test it on sandbox instead of real money.

Fixed value works perfectly, but variable price from “value” gives me the error. Could you try to check if does it work for you with “price” variable in paypal payment?

another update:
I created a similar form and tested all the errors that i faced before. Fixed value in the payment works, but problem appears when i try to use value from “calculation” field. The error “Error! Invalid payment amount!” appears only when I use decimal values in “calculation” field. I checked my calculations as well and they are all working properly. The problem is all about the decimal values that paypal field doesnt accept. How can i fix that if its not from my side?

Hi @sagithereal

PayPal was having some issues this week, I can see in their status that it is now fixed.

I was able to see the issue on calculation and we escalated this to our Second Line Support team.

Can you also double check your Formula?

There are some instances that the price is negative and I don’t believe it is expected: https://monosnap.com/file/Ck6ej9NZHcW5cnC0IVoFClgRRrlUnt

calculations are fine. this site is all about eloboosting so noone will buy a boost backwards anyways. Negative values arent problem now, but the decimals are.

Hi @sagithereal

I checked the form and there’s one more thing to take care of. It shouldn’t matter but I know it was causing some issue in the past, especially in case of complex calculations and/or calculations based on conditionally visible fields.

Specifically, the “Price” field is set to use the 12345678.98 format with two decimals but quite a lot of values used in calculations use 12345678,90 format (“dot” versus “comma”). The problem is that while in some formats the point/dot is used to separate decimal part and in some other comma is used for that, there are also formats that use comma to separate thousands (like 12,500.75 would be twelve thousands five hundred and decimal part of 75).

It shouldn’t be an issue but please make sure that format used throughout the form is consistent and the same (may it be “comma” or “point” – but the same everywhere).

Kind regards,
Adam

Hi @sagithereal,

Could you please try the following snippet and see whether it helps with resolving the issues noticed in the calculations?

Snippet:
https://gist.github.com/wpmudev-sls/3b3da48ebc54d05ddce09dfda6ff3919

You’ll need to add the above code as a mu-plugins. Before implementing the code, you’ll need to edit the code to change the form ID on line 24, ie:

		$form_id   = 314;

Change the above line, to your form ID. If your form ID is 123, the above line would be:

		$form_id   = 123;

Once done, on your WordPress dashboard side, please load the following URL:
yoursite-url.com/wp-admin/?formi_fix_value_whitespaces=1

Please make sure to replace yoursite-url.com in the above to your website’s URL.

Once done, you can remove the given snippet from the mu-plugins and then check whether the form works.

Please check this link on how to implement the above code as a mu-plugins:
https://wpmudev.com/docs/using-wordpress/installing-wordpress-plugins/#installing-mu-plugins

Please do let us know how that goes.

Kind Regards,
Nithin

Hello @sagithereal ,

We haven’t heard from you for several days now, so it looks like you don’t have more questions for us.

Feel free to re-open this ticket if needed.

Kind regards
Kasia

well, after implementing the snippet, the error still appears
I implemented every single fix step by step, even on brand new form that was made just for tests. I also changed the ID of both forms, but sadly the error still appears

If the price is a whole number (integer) f.e “1,0€”, the payment is processed, but if I add another “0,5€” f.e by using the checkbox, the same error apprears again.
