Install the following event macro in the code area of the source sheet:
Private Sub Worksheet_Deactivate()
Range("A1").Copy Workbooks("beta.xls").Sheets("Sheet3").Range("B9")
End Sub
Once you de-activate the source sheet the value will be copied as indicated.
To de-activate, just click on some other tab in the source workbook.
Because it is worksheet code, it is very easy to install and automatic to use:
1. right-click the tab name near the bottom of the Excel window
2. select View Code - this brings up a VBE window
3. paste the stuff in and close the VBE window
If you have any concerns, first try it on a trial worksheet.
If you save the workbook, the macro will be saved with it.
To remove the macro:
1. bring up the VBE windows as above
2. clear the code out
3. close the VBE window
