Hi Lostcowboy, Thanks for the links, but, alsas, I'm not sure I'm up to it at the moment. Both time and energy are a bit in short supply at the moment, but I will keep it in mind.
The biggest problem is the differences between the way VBA is used in *.xls and *xlsm, the more recent version that runs VBA. Apparently *.xlsx does not run macros.
Best,
Allen
