Multi auto populate AND validate before sending - how?

[rainl92869403]

I have a long form that has 'user info' and 'supplier info'. This form has 3 check boxes, with 1 needing to be selected. 2 of the check boxes would auto populate this section with either the 'user info' OR 'supplier' info the 3rd check box would leave that section of the form empty allowing the 'translator' to fill their info.

How do I do this?

On completion the form MUST validate before sending...

You would need to use a script that populates the fields based on the selection (and makes them read-only), or clears them and makes them editable. You can manually set the fields as required to make sure they are validated when the form is submitted.
