PayPal integration not working: Unable to select a product

I have cloned your form and I can see that there is a problem with the payment field. I am unable to choose any product.

It is possible that the "Required" function is set to "Yes". Please follow the steps below to fix it:

1. Select the payment field and then click the wand icon.

2. Select a product and then click the "edit" icon.

3. Disable the "Required" function. Set it to "NO".

4. Save the changes by clicking the "Save Product" button.

5. You also need to do this in the other products.

Here's the result:

Hope that helps. If you need anything else, let us know. Thank you.
