So close -- try something along these lines:

Function ShowIt()
Application.Volatile
ShowIt = Sheets(Application.Caller.Worksheet.Name).Range("A 1")
End Function

Is there anyway to limit the function so that it runs against the sheet it
was entered on rather than running against the active sheet?

I've tried looking around for this and have discovered the following which
don't seem to work...unless I'm using them wrong :-)

Application.Caller
Application.ThisCell.Worksheet

Any ideas?
