Thread: increment of formulas

I cant get this one right,

In colom A, row 1 I have this formula:
=COUNTIF('[DAILY REPORTS AND ROUTES.xlsx]1'!$M$4:$M$8,"Y")
colom A, row 2:
=COUNTIF('[DAILY REPORTS AND ROUTES.xlsx]2'!$M$4:$M$8,"Y")
colom A row 3:
=COUNTIF('[DAILY REPORTS AND ROUTES.xlsx]3'!$M$4:$M$8,"Y")
Now my question:
1)How can I drag colom B-G so the formula automaticly change the cell ref to the next one, eg
=COUNTIF('[DAILY REPORTS AND ROUTES.xlsx]1'!$M$4:$M$8,"Y")
becomes
=COUNTIF('[DAILY REPORTS AND ROUTES.xlsx]1'!$N$4:$N$8,"Y") and so on?
OR can I drag th rows and the sheet ref changes automatically from 1 to 2 to 3 to4, etc?

I hope this make sense, I have about 12 sheets with 100 values each to change by hand if there is no other way!

1) Dragging the formula
You can try =COUNTIF('[DAILY REPORTS AND ROUTES.xlsx]1'!M$4:M$8,"Y")

When you drag it to the right the col ref will change automatically ( see absolute and relative references)

Try something like

=COUNTIF(INDIRECT("'[DAILY REPORTS AND ROUTES.xlsx]"& CELL("row",A1) & "'!$M$4:$M$8"),"Y")

Change the A1 to the address of the cell in which the formula is placed.
