I think I'm missing something very basic here :( - My 1st sheet "Time Pred" -> MY SHEET LINK
Trying to get formula in Col E to change every 24 rows- it should refer to Col D cells corresponding to Col C value being 1, 13, 24 - the nearest ones.
So in linked example: E3 to E26 have a formula ; then E27 to E50 the formula changes (I've pasted the right formula I want there) - it references the Col D values as explained above.
But right now I have to manually change formula every 24 roes to make it look at the desired values - looking for help to redefine formulae so it changes as I drag it down as there are over 12000 rows in final sheet.
Detailed explanation:so in my sheet, if u see cells E3 to E15 - formula takes time value in those 2 cells and divides into 12 equal time periods and assigns that time to cells E4 to E14 (proven by control col F that counts duration between successive rows)
Similarly for next 12 cells - formula takes time value in those 2 cells (E15 & E 27) and divides that time into 12 equal time periods and assigns that time to cells E16 to E26 -
Now for next 12 cells- it should work likewise- so it should now refer to cells E27 to E39 - take time value in those 2 cells and divides that time into 12 equal time periods and assigns that time to cells E28 to E38.
Col F tells us if formula achieves desired results - which means duration will be constant every 12 periods (shown by Col C)
