Hi, I was trying to make a conditional formatted attendance sheet. The idea being to have a visual warning if students have missed a certain number of classes so far. It worked fine in excel 2007 but when someone tried to open it in excel 2010, it all blew up.
The formatting formula which worked in excel 2007 is
=COUNTIF($E6:INDIRECT($A6),"-")>2
where A6 stores the value "M6".
When I tried the same thing in excel 2010 it said: "You may not use reference operators (such as unions, intersections, and ranges) or array functions for Conditional Formatting criteria"
To better explain what I'm trying to do I've included a copy of the spreadsheet which worked in excel 2007
Any know how I could change this to work in excel 2010?
Thank you!
