Hi Gary,

DvFilterDefault = DvFilterError + DvFilterCorrect + DvFilterConclusion + DvFilterAll
* Or 
DvFilterDefault = BITOR(DvFilterError, DvFilterCorrect, DvFilterConclusion, DvFilterAll)

The first form will work if constant don't intersect (represent different bits). The second should work always. Keep in mind that if there are constatnts with high bit set (0x80000000) you may have to cast it to integer using

BITXOR((BITOR(DvFilterDefault + DvFilterUnViewed)),0)
