You posted in the tablesdbdesign newsgroup, but this is most likely not a
tables-related solution...
One approach would be to create three procedures, each with a message box,
one for each condition. I assume you have the starting date somehow stored,
as the queries would need to "know" 60 (or 75, or 90) days from what?
Take a look at the DateAdd() function to see one way to, well, add days to a
date. Then compare to the current system date using the Date() function.
