I have 3 text fields, 'address', 'postal Address' and 'postalAddressSame'.

postalAddressSame is a Yes/No radio button. What I want to achieve is that if postalAddressSame=Yes then the contents of address are copied into postalAddress.

Originally I had postalAddress as a calculation but this doen't allow the user to enter data if postalAddressSame is 'No'.

So now I have a script that check status of postalAddressSame and either pastes address into postalAdress orr pastes "".

How do I attach the script to the radio button so that if Yes or No is clicked the script will run? (using FMP 5)

Thanks in advance

I'd use a calculation. You'll need fields:

Address

Postal Address Entry

Postal Address (calculation) =

If(postalAddressSame = "Yes", Address, Postal Address Entry)

Put the Postal Address Entry field UNDER then Postal Address field. Make the Postal Address field a button defined as "GoToField(Postal Address Entry)"
