The attached has a form called "frmProperty"
The main form contains a field called "units" that represent the total units in the building. So for the first property, that field says the building has 40 units.
The subform "subfrmVacyUnits" totals the number of "units by type" in the form footer. That field is called "SumUnitNo." In the first property, the units by type total 33.
Based on the above, we are missing 7 more units.
I would like the field in the subform "SumUnitNo" to turn bright yellow (or whatever color) if the "SumUnitNo" does not equal the field "units" in the building.
Is there a way to easily do this?
