The formula I'm trying to fix was not reporting our information correctly so I built a new formula in a test environment and it appeared to be working as intended only for me to find that when applying it in a live setting, the result was constant #INVALID OPERATION errors.
The formula is this:
=IF([Est. Annual Rent]@row = 0, " ", IF(SUMIF([Project No.]:[Project No.], [Project No.]@row, [Est. Annual Rent]:[Est. Annual Rent]) < 280000, "LEVEL I", IF([Project Aggregate Total Contract Value]@row < 10000000, "LEVEL II", IF([Project Aggregate Total Contract Value]@row > 10000000, "LEVEL III"))))
I made another version two with a modification to the end of the formula to see if that would help (It didn't):
=IF([Est. Annual Rent]@row = 0, "", IF(SUMIF([Project No.]:[Project No.], [Project No.]@row, [Est. Annual Rent]:[Est. Annual Rent]) < 280000, "LEVEL I", IF([Project Aggregate Total Contract Value]@row < 10000000, "LEVEL II", "LEVEL III")))
What I've Tried:
- In both the testing and live environments, all the column types are Text/Number.
- I switched the SUMIF to SUMIFS (As well as switching the range/criteria ranges to match what the function calls for)
- Rewriting the formulas from scratch to ensure syntax wasn't the issue (It still may be)
