I suppose the simplest way would be to copy the macro from personal.xls to
the other workbook and then use the Workbook_Open method to run the macro.
If your macro is in the code module, you open the module with Alt+f11 while
you have both workbooks open. In the project window on the left of the
screen you can select the code module for Personal.xls to get the code you
want to copy and then scroll to the code module for the other workbook and
paste the code in that workbook code module. Then save the workbooks and the
macro will be available in both workbooks.
If this is confusing to you, you need to get someone in your office who
works with code to help.
