I have an Excel formula that works fine in excel 2003 but in Excel 2016 I get the error when clicking on Data Validation.
"You may not use reference operators (such as unions, intersections, and ranges) or array constants for Data Validation criteria"
My formula is
=INDIRECT("IQ!"&LEFT($T28, 2)&"11"):INDIRECT("IQ!"&LEFT($T28, 2)&11+$V28)
I had to do the formula like this, as the business users cannot update the formula themselves. I have a dropdown list in another sheet within Excel, which this refers to.
