Well, at it's simplest:
..Select the target cell (i.e. the one on your Summary sheet you want to have
updated automatically),
.. press the '=' sign
.. select the source cell
.. press <Enter
Now the two are linked and the value on the Summary sheet should update
whenever the source cell is updated. In essence, the procedure is the same
as you might use with the mouse to reference another cell on the same
worksheet - the only significant difference is that you're selecting another
worksheet's tab along the way.

Hi macropod,

I'm trying to figure out how to do this (formula linking to others).

Thanks.

Hi srpettew,

Assuming you summary sheet has formulae linking to the others, the data
should update automatically anytime the worksheet re-calculates.

Hi,

I have several tabs (worksheets) representing purchases for a specific
year.
There is one tab (worksheet) that is a Summary of all purchases for
all
years. How do I get Excel to automatically update the Summary
worksheet
anytime one of the other worksheets are modified?
