How do I link the range of a comboboox to the results from another combobox. For example, I have a form I use to record time intervals over the day. If I select 9:00 for the first combobox, I would like the next combobox range to start at 9:00 instead of the default range 6:00. as I have 35 time intervals, I would like to place a formula in the combobox formatting screen rather than create 35 individual ranges.
