>>Yes, if you are testing the value of the option button that is or is not selected then you have to test for the this.option1.value as 0 or 1. If you want to use the value tested to change your field value to a YES or NO you could do it like this,
>>
>>If this.option1.value=1 &&If option1 is selected
>>replace actcompl.nontrad with "YES"
>>else
>>replace actcompl.nontrad with "NO"
>>endif
>>
>>
>>This will give you the Yes/No in the field that you are looking for.

>>Hope this helps.
