OK. In the thisworkbook module put in a workbook_open macro to run the macro
and put todays date somewhere. Have the macro check to see if the date is
later or not run.

I want to setup a macro, in a file, that only run once on a specific day
of
the week regardless of who first open the file. The macro needs to run
only
once, every monday, the first time the file is open. Any subsequent
opening
of the file after that, the macro should not run.
How do I go about setting this up? I just need someone to point me in a
generally direction and I should be able to take it from there.
Thanks
Ayo
