Ok.. so this is a little complicated. I currently have an If statement written that says if abs(T-M)> 1 and W < 1, then execute function “C”.The issue, is that isn’t quite exactly how my process shouldwork.

What needs to happen, is it needs to determine the highestschedule before it reaches 100. So for sched 1, that’d be year 5. For schedule2, year 3. The script would say if T < Y4 (for example) and if abs(T-M)> 1, then execute function “C”. My sheet withdata does not have schedule # on it. Instead it has ‘source’ in column U. Ihave table with the following on the instructions tab as well.
Source | Schedule

What I know needs to happen is a vlookup of source (columnU), against the instructions tab columns H:I to determine the schedule. But, Inot know how to determine which year (%1, %2, %3, etc.) is the last year beforeit reaches 100.

To complicate matters… on the schedule 0 where it isimmediately 100, I want to possibly determine out of all schedules, what is thehighest year # (%1, %2, %3, etc.), before there is a 100%. Sorry if this doesn’tmake total sense.. I’ll be around for questions!
