Indirect Addressing of Worksheets

Probably an easy question, but I can't find the answer in the Excel Help
files.

I want to be able to construct a worksheet reference from the contents
of a cell.

For example, I have 2 worksheets called "Week1" & "Week2". I have a 3rd
worksheet called "Data".

If "Data!A1" is equal to "1", I want "Data!B1" to equal "Week1!B1".

If "Data!A1" is equal to "2", I want "Data!B1" to equal "Week2!B1".

I would have thought that Excel contained some indirect addressing
capabilities, but I can't find it.

Hi!

If you have described the full extent (or thereabouts) of the problem,
try:

In cell Data!A1 put =IF(Data!B1=1,Week1!B1,IF(Data!B1=2,Week2!B1,""))

Hi,

Try putting this formula in B1 of your Data sheet:

=INDIRECT("Week"&A1&"!B1")

Hope this helps!

Thanks AlfD, however I will have 52 worksheets "Week1" to "Week52". I
just used 2 sheets in my example for brevity.

one way:

=INDIRECT("'Week" & data!A1 & "'!B1")

The apostrophes (') are really only required if the sheet name may have
a space in it.

Hi!
Quite! I thought there would be n other sheets waiting to ambush me.

So: the following does the sort of job you want. May need a bit of
refining. It assumes you are continuing your (useful) sheet numbering
system.

Put ="Week"&B1&"!"&"B1" in A1.
Put the number of the sheet you want to invoke in B1
Put INDIRECT(A1) in C1

C1 will show you the contents of B1 on the chosen sheet.

Thanks to all who responded.

INDIRECT is the answer to my problem. I don't know why I couldn't find
it in the help files; I must have been more tired than I thought.
