I can't copy a field value into a paypal input

Hi,

I'm trying to write a conditional statement where if a user chooses the option of "mailing by check" that the total shown on the paypal currency input would be 0 so they won't be charged. However, when I write the conditional statement paypal always shows the total price. Is this is a bug or can conditional statements not affect USD inputs for paypal? 

Thanks,

Sofia

I have checked your JotForm and see that the PayPal field is configured with products. In order to pass a custom value to the payment field, it is required to use User defined amount in the payment field by setting up the products separately. Please refer to the guide below that might help in passing a value to payment field.

Since you do not want to process the payment using PayPal if 'Mailing by check' option is selected, you may set up the condition to Show/Hide the payment field instead of passing the value 0. If the payment field is hidden, the PayPal field will be ignored.

Hope this information helps!
