Hi @saz25,
Replacing that text on a form by form basis would require a bit of custom code, that you can see here:
https://github.com/impress-org/givewp-snippet-library/blob/master/translation-snippets/change-text-locally-per-form.php
Lines 17, 18, and 33 would need some editing before you use that code in production.
The string to target on line 17 would be ‘Leave a comment’
Then make sure you enter the form ID for the Form on line 33.
If you need assistance implementing custom PHP code on your website we have this guide:
https://givewp.com/documentation/resources/adding-custom-functions-to-your-wordpress-website/
Please note that this code snippet is provided as an example of how you can extend GiveWP with code. It’s up to you to implement and customize to your liking. We cannot provide support for custom code on your website, only the code that we create and distribute.
Let me know if that resolves things, or if you need further assistance. Thanks for using GiveWP! Have a great day.
