Increment a counter in Excel

[COSdl]

How can I increment a counter in a worksheet cell from the value entered in
other cellsl? For instance if the value in cell A2 = true I want to replace
the value in B2 with the value in A1(the counter), then increment the value
in A1 by 1. The worksheet might look like this:
A B
1 4
2 TRUE 1
3 FALSE
4 TRUE 2
5 TRUE 3
6
7

Try this:

1. Copy this into A1:

=COUNT(B:B)

2. Copy this into B2 and fill down the column as far as
you think you'll need it:

=IF(A2="","",IF(A2,MAX($B$1:B1)+1,""))

3. Star filling in col. B with TRUE/FALSE

Thanks, Jason. This is almost it! I also need to increment the counter in
A1 (which will actually be on another spreadsheet. Each sheet will use the
counter on sheet!A1. I am assigning a number to each "true" which could be
on multiple sheets. Also, I think you meant for your #3. instruction to be
"Start filling in col. A" rather than col. B???? This is what my spread sheet
looks like now:
A B
1 0
2 TRUE 1
3 TRUE 2
4 TRUE 3
5 TRUE 4
6 TRUE 5
7 TRUE 6
8 TRUE 7
9 FALSE
10 TRUE 8
11 FALSE
12 TRUE 9
13 FALSE
