One way (manual) is that each time you add a sheet then do Find/
Replace on all the cells in Sheet1 that contain a formula and change
Sheet10 to Sheet11, and so on.
Another way is to use a single cell on Sheet1 to record the name of
the last sheet added, eg put "Sheet10" (without the quotes) in cell
X1. The your formula above would become:
=SUM(INDIRECT("'"&$X$1&"'!A1

1"))
Note the apostrophes are there to allow you to have spaces in the
sheet name.
Now if you add a new Sheet11, you just need to change the value in X1
to Sheet11 to get the formula to change.
Hope this helps.
