I would like to run a macro, "Perform_Tasks", on a scheduled basis. I would
like users to be able to select certain criteria for this macro, as such:

A B C....
1 Enable/Disable: Enabled
2 Interval: 15
3 Begin Time: 07:00
4 End Time: 13:00

B1:B4 would be user changable values and would dictate how often the macro
kicks off automatically, if enabled. (B1 is a toggle switch between Enable or
Disabled).

Any suggestions?
