    Dynamic formulas IF/LOOKUP?

    Hi!

    I will have excel to calculate the percent change between to values where an improvement is always shown as a positive value and a decline is always shown as a negative value. My problem is that I want excel to calculate this between the to latest values only i.e. if column J is blank, calculate with column I and H etc. also if a player misses a test and column J is blank but so is column H, then it would be really nice if excel could use the data from I and G.

    I have absolutely no idea how to write a dynamic formula like this. I am familiar with IF formulas but I couldn't find a way for that to work :/

    Anyone able to help me? I attached a simple workbook with some numbers to calculate on.

    Thanks!

    Markus

    hi anghicole. try this array formula:
    =LOOKUP(2,1/(D2:N2<>""),D2:N2)-INDEX(D2:N2,LARGE(IF(D2:N2<>"",COLUMN(D2:N2)),2)-COLUMN(D2)+1)

    ...confirmed by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. You will know the array is active when you see curly braces { } appear around your formula. If you do not CTRL+SHIFT+ENTER you will get an error or a clearly incorrect answer. Press F2 on that cell and try again.

    and change all my commas to semicolons if your separators are the latter

    Hi,

    I would've thought the percentage increase/decrease should be measured viz:

    (Latest Score-Previous Score)/Previous Score

    Non-array alternative to do this (in O2 and copy down):

    =SUMPRODUCT(N(OFFSET(D2,,LARGE(INDEX((D2:N2<>"")*(COLUMN(D2:N2)-MIN(COLUMN(D2:N2))),,),{1,2}),,))*{1,-1})/OFFSET(D2,,LARGE(INDEX((D2:N2<>"")*(COLUMN(D2:N2)-MIN(COLUMN(D2:N2))),,),2),,)

    XOR LX, you're totally right! I did get some strange percentages on some of the results. Your formula works perfect, and with a correct calculation of the percentages! Thank you so much for the quick correction!!
