I could do this in straight javascript but can't figure out an easy way to do it with DF.

I have a form with a set of 10 fields for names and another 10 for grade level. The name field is a text box and the grade level field is a radio button group. We are getting the names of members of a project group and they grade level. We want to be sure that anyone entering their name on the form is required to select a grade level option.

The problem is that some teams might have as few as 2 peopls and other teams have up to 10. So there is no fixed number of members where I can turn on the validation for each question.

Is there a way I can validate one field only if the preceding field has data in it? The only thing I have come up with on my own is to introduce another field where the user selects the number of people on the team - whereupon a question event fires and enables the number of fields to correspond with the user selection.

Any ideas?

Many thanks in advance.
