I'm using SUMIFS(), and I want the criteria1 to be the first number of a series of comma separated numbers within a cell. For example,
A1=1111, 1112 SUMIFS(B:B, C:C, A1)
So basically, the formula should add all the cells in B:B that are adjacent to each cell in C:C that has the value "1111", but I don't know how to specify to the function to use 1111, but ignore 1112. Its one of those syntax rules that only expert Excel users know about. :)
You will need to parse the data:
=SUMIFS(B:B, C:C, TRIM(LEFT(A1,FIND(",",A1)-1)))
