Here is the formula I have:
{MLI (Sq. Ft.)}*1.50+{Bluemaxx AC Re-New (Ounces)}103+{Attic Air Seal (Energy Saver)}.32+{H20 Wrap}*75+{Power Perfect Box}*1500+{Solar Fan}*785+{NEST Thermostat}*349
It is working perfectly when all of the fields are filled out. However, if there is on single field that isn’t filled out, I get an #ERROR!. How do I bypass, or ignore a blank field. I want the formula to calculate regardless if they’re all filled out or only one is filled out.
