I have a evaluation form that I NEED help with. There are 4 Rating levels to choose, E, S, NI, and NA with a value of 3, 2, 1, and 0. Each Category (Blue row) has subtask (Green rows) with a percentage weight for each. In the example below, you can see in Column F that each weight is 25% for all 4 subtask. When I make the last task an NA (cell C13), then the other 3 subtask weight changes to 33.33%, If I change 2 to NA then the remaining changes to 50%. Easy as there are only 4 subtask and each are 25

But on the following Category, there are 7 subtask with different weight (20%, 15%, and 10%). So on this one, if I make a subtask NA, then that weight needs to be distributed to the other 6 subtasks but keep the same ration.

So making subtask 1 an NA, then the other 6 task would need to be their original % (Column E) PLUS and additional 4%(20%/6) So 10% changes to 13.3 and 15% changes to 18.3. If I then also make Subtask 6 an NA, then the remaining 5 will get and additional 7% (35%/5 [20 and 15]). So whichever subtask is made an NA, the remaining task need to change appropriately.

Hi,

You can use this array formula (add with ctrl+shift+enter, Excel will add { } around it when done correctly)

First it sums up all the %for rows with have NA rating, then it divides the remainder by the number of non-NA ratings and adds this to the base

'scores' is your column of ratings and 'basew' is your column of base weight %s
