I'm needing assistance, trying to have the formula for the cell first look in a sheet for a check box, then look back in the original sheet for an AND value, then for the true statement do an Index, Match. I have tries multiple combinations but can figure it out, here is what I currently have:
=IFERROR(IF(AND({Study Device Inventory by Country Range 3} = "True", [# Tablets]@row > 0), INDEX({Study Device Inventory by Country Range 1}, MATCH(Country@row, {Study Device Inventory by Country Range 2}, 0)), "-"))
