enabling/disabling data entry in a field at runtime

[Doubledunk]

Hello community, I was wondering if you could help me with the following scenario.

Is it possible to enable or disable a field based on another field's input? For example let's say I had a field with a payment option of cash or credit card, and another field with a credit card number. If the payment option is cash then the credit card field would would not accept any data entry. However if payment option is credit card then the credit card number field would accept input.

Is this possible in filemaker? Thank you for all your help.

How about using the Visibility approach, seen Here by John Mark Osborne

Thank you for your reply Lee. However, I am unable to access that page. It gives me an "unexpected error" message. Could you perhaps elaborate on the visibility method? perhaps a sample file?

Thank you in advance
