I honestly couldn't understand your requirements. They're quite confusing.
I KNOW it's confusing and I apologize...it's confusing to me!
...which is why I need help sorting the logic out. THANK YOU for digging into this mess.
Let me confirm some things first.
1) Screen Size <> 0 AND Helper = "" THEN "Missing Data"
Helper cell (E column) was left blank and needs answered, either Y or N. This works.
2) Screen Size <> 0 AND Helper = "Y" THEN ""
Helper cell has been satisfied with data and no further action is necessary. This appears to work.
3) Screen Size <> 0 AND Helper = "N" AND Screen Size < 42 THEN ""
Helper cell has been satisfied particularly since the TV Screen Size is under the company requirement of needing a helper and no further action is necessary. This appears to work.
4) Screen Size <> 0 AND Helper = "N" AND Screen Size > 41 AND K = "Cancel*" THEN ""
← This is where the formula is not doing what I need it to do. IF Screen Size = something and the Screen Size is greater than 41” AND Column K = cancel (The technician acknowledges that the work order was canceled), then leave Column Q blank (Column Q is my "error catching" notification cell). Instead the formula (see cells Q4 and R4) is displaying Δ to Y (change to YES). What I think I need to clarify for you to understand is that if the work order was canceled, then the technician wasn't on site to see the TV so there’s no possible way the technician can say, YES or NO, I had a Helper or if the TV was mounted on a wall. If you change cells E4 and F4 to N/A ...similar to ROW 3, then it works.
Here’s where its starts getting confusing:
5) Screen Size <> 0 AND Helper = "N" AND Screen Size > 41 And K = "" THEN
Δ to Y"
The technician is reporting there is no helper, and by company requirements, he must have a helper if the TV Screen Size is greater than 41", therefore the reminder to put YES and the note in Column Q to Δ to Y (change to Y).
6) No clue what "Else Blank"/ "Confirm N/A" depends on
In cells Q3 and R3 it seems to be working as the work order has been canceled and "Confirm N/A" indicates that because it is a canceled work order the Helper and Wall Mounted questions have been confirmed as Not Applicable....but it also correctly says N/A in cells E3 and F3. If you change E4 and F4 to N/A, they work as well, but not with N as an answer, hence where the formula breaks down.
Does this help you?
