I might suggest a couple ways, but not sure exactly what your trying to do.
Here's one example.
In the VB Editor "Project Explorer", right click on "ThisWorkbook", and
select "View Code". Click the drop down box on the left side, and pick
workbook. Now click the right drop down box and select
"SheetSelectionChange"
add the following code
If ActiveCell.Value = "test" Then
Range("B1").Value = "test"
Else
Range("B1").Value = ""
End If
Now, go to cell "A1" in your worksheet and type the word "test" (without the
quotes)
Now watch what happens in "B1" when you click the mouse on any cell except
"A1", then try clicking on "A1".
Is this anything like you're looking for? You can use other workbook events
to trigger your code. Look up "workbook object" in the VB Editor Help menu,
then select "Events"
Did this help?
