Change thank you page condition problem.

I have a field (paypal integraion) and the value is a number

I want to change the thank you page according to the value

if set to 0 (zero) show a different "thank you" page 

the problem is that once i select the filed it's not allowing me to set the value, it shows a dropdown list saying "Please select a product"

With the payment field, you can only use a condition like that, to check if it is equal to the selected product.

But you could create your donation options with a radio button:

And assign calculation values (which will be donation amounts).

Then you could add Form calculation widget in which the donation will be calculated:

Finally, that calculation can be passed to the payment field.

With this setup, you can create the condition that you wanted (by using the radio button).

Let us know if you have any further questions.

Thank you!

Hi I've taken your advice and added a calculation field, no need to set the radio buttons 

it is working as expected as is.

Thank you
