InfoPath Dev

 Thanks Bre I'll definitely give this a try.

Working with InfoPath 2007 (sorry) browser-enabled form.  I have an option button with two options: 'Current customer' (value when selected=1) and 'Prospect' (value when selected=2). If the user selects 'Current customer' I would like to jump to the first field in the 'Current customer' section; if they select ...

I have two text boxes, A and B. Both cannot be null and both cannot be populated. I am having issues with writing the conditions to force the user to populate only one text box and preventing them from populating both or leaving both blank. Any assistance would be appreciated.   MaryannD
