I have changed it so that it is numeric, it still gives me the same error.

In my init method I have thisform.r_rateuni = 2, I want the optiongroup to default to the second choice which is 'No'.

the controlsource is thisform.r_rateuni.

If I change the controlsource to a variable that is used in the optiongroups that was original on the form, thisform.r_chead it works fine. In the init method thisform.r_chead = "Yes"

I have tried assigning thisform.r_rateuni the same way. I have also tried deleting the control and recreating it to see if something maybe got corrupted with it.

Please....any help wwould eleviate a great deal of frustration at this point!
