Automatically move cell reference over: How can I do this in Excel without manually updating the formula each week?

Question

I have a sales tracker spreadsheet and am trying to figure out how to create a formula where each week's sales is multiplied by the retail. However; the cell reference would need to move over by 1 cell each week. For example: BN=AE4*F4 where AE4 is last week's sales and F4 is the retail of the item. When I update the report for next week, I would like for the formula to read as BN=AF4*F4 . How can I do this in Excel without manually updating the formula each week?

Answer 1

要将F4乘以第4行中的最后一个数字（从左到右读取），请使用此公式。

=F4*INDEX(4:4, MATCH(1E+99, 4:4))
