I have a worksheet which looks something like this:

1645451958443.png


Cell B1 has the formula

Excel Formula:
=ISOWEEKNUM(TODAY())

And B5 has the formula:

Excel Formula:
=IFERROR(INDIRECT(B1&"!B5";TRUE);0)+IFERROR(INDIRECT((B1-1)&"!B5";TRUE);0)...+IFERROR(INDIRECT((B1-9)&"!B5";TRUE);0)

Is there any way to simplify the formula in B6, or am I stuck with what I have if I want to sum the cell over the last 10 weeks?
 

Excel Facts

Formula for Yesterday
Name Manager, New Name. Yesterday =TODAY()-1. OK. Then, use =YESTERDAY in any cell. Tomorrow could be =TODAY()+1.
