I am trying to use VLOOKUP in this Google Sheet to convert percentage grades to a 1–8 grading scale. I would like to be able to differentiate between a score of 0 and an empty score but am having trouble making this work.
Here's the current formula I'm using: =IF(ISBLANK(VLOOKUP((C2/$C$6),'Grade Boundaries'!$A$3:$B$10,2,true)),"",VLOOKUP((C2/$C$6),'Grade Boundaries'!$A$3:$B$10,2,true))
Current behavior
The Adjusted column shows 1 whether the corresponding Raw value is 0 or blank.
Desired behavior
The Adjusted column should show 1 if the corresponding Raw value is 0, or N/A if the corresponding Raw value is blank.
I've tried looking at other suggestions here and using IF statements, but I seem to keep getting stuck with the fact that VLOOKUP doesn't appear to differentiate between a value of zero and an empty cell.
