Hi, I'm new to zoho, and I have a question.

In the invoice format, I put a field called payment method. If the customer chooses cash, a tendered field should be displayed. If the customer pays by card, the credit card type field should appear. I already achieved that when the form was loaded, the fields were hidden, but I have not been able to show them with that logic. I made this code, but it only worked for me and only with cash the first few times, and then no longer. Any ideas?. Thank you so much
