Custom Validation - At least 1 field filled

Hello,
I got a form with 9 textfields.
Is there a way to validate that at least one field is filled?

Hi Gatsman,

I think you'd need to use a Custom Validation function and add the name of the function to the Custom box on the Validation tab of each element. Otherwise you could perhaps write a separate custom function and run that when the Submit button is clicked?
