I have an issue using the average formula (example attached). I need to calculate the average grade of a group of students. I have used VLOOKUP to convert grades to numbers. Then averaged these results and converted back. It appears to work for most results, but some are not working. I have messed about with cell formatting etc, but cannot seem to figure out why its not working for some rows but does for other rows?
Any suggestions welcome.
Thanks
