I am trying to filter on 3 'AND' conditions and the custom filter is not working as expected.
!IsNull([`Dec2])
AND !IsNull([Inv #])
AND [Vendor_Site]IN('YES')
When I comment out the 3rd condition the filter works as it should. I have tested each condition by themselves and they are working appropriately, it's just when I add a third condition that the filter messes up.
Any thoughts as to why this is occurring and how I can correct it?
