On sheet1 A1 is a cell with dropdown where you can choose a tile.
This title at times may or may not come up in sheet2:sheet7 with 30 rows of data below it.
I would like when I change the tile on sheet1 in A1, the sheet finds the matching title in all sheets 2-7 and sums all related data points in the 30 rows below from the other sheets.
For example:
If "Sheet1 A1" is selected "Title 1" from the dropdown, "Sheet1 A2:A31" is the sum of all "A2:A31" cells with matching "A1's" in Sheets 2-7. Note that in Sheets 2-7 the matching data may not be in column A and could be anywhere on the sheet. If "Title 1" does not find a match, value is 0
IFS()
function would do it for you...
