I'm stumped on a formula and I feel like it's probably an easy fix I'm just not seeing. I have a sheet with various date columns, and I want the formula to check to see if that date is within 180 days of today, and if it is, I want it to return Alert. However, the date isn't populated for every row, so if it's blank I want it to return "", and if the date isn't within 180 days of today I also want it to return "". I think the way I set it up it's only checking the first set of logic and my brain can't wrap around what I'm doing wrong!
=IF(ISBLANK([Home Energy Prof BPI Cert Exp - Energy Auditor]@row), "", IF([Home Energy Prof BPI Cert Exp - Energy Auditor]@row - 180 < TODAY(), "Alert", IF(ISBLANK([Home Energy Prof BPI Cert Exp - QCI]@row), "", IF([Home Energy Prof BPI Cert Exp - QCI]@row - 180 < TODAY(), "Alert", IF(ISBLANK([Lead RRP Firm License Expiration Date]@row), "", IF([Lead RRP Firm License Expiration Date]@row - 180 < TODAY(), "Alert", IF(ISBLANK([VA DPOR Resident Building Energy Analyst Exp Date]@row), "", IF([VA DPOR Resident Building Energy Analyst Exp Date]@row - 180 < TODAY(), "Alert", IF(ISBLANK([Master HVAC Expiration Date]@row), "", IF([Master HVAC Expiration Date]@row - 180 < TODAY(), "Alert", IF(ISBLANK([VA Contractor's Expiration Date]@row), "", IF([VA Contractor's Expiration Date]@row - 180 < TODAY(), "Alert", ""))))))))))))
