If else code and input field value store into variable

Hi,

If you are using any of the paid versions of the plugin it is possible to associate a thank you page to the form, and in the thank you page insert a shortcode to display a summary with the information submitted.

In reality I don’t understand your equation, but I will assume you want to display the submit button if the sum of fields: fieldname1, fieldname2, fieldname3, and fieldname4 is bigger than 5 and less than 20, in this case:

I will insert the four number fields, a calculated field to be used as auxiliary (the field won’t be relevant in the form’s interface, so, should be ticked the attribute to hide it from the public web page), and a button field with the special class: hide

The onclick event assigned to the button would be as simple as:

jQuery(this).closest('form').submit();

and the equation associated to the calculated field:

(function(){
var result = fieldname1+fieldname2+fieldname3+fieldname4;

if(5<= result && result <=20 ) jQuery('.hide').show();
return result;

})()

Furthermore, you have created a different webpage with the texts, graphics, and the summary shortcodes. Enter the URL of the new page as the “Thank you” page in the form’s settings (after the form be submitted, the user is redirected to the thank you page).
