I have a formula that calculates the amount of time elapsed of 15 minute
increments...The formula is part of a grid that looks like this:
7:30 a 7:45 a
7:45 a 8:00 a
etc. until
4:45 p 5:00 p

It sources from a "Time In" and "Time Out" section. Users record time, for
example, like this: 7:30 a for Time in and 12:00 p for time out. The formula
in question then fills in 15 minute ranges with the amount of time.

I added another set of time in and time outs so I have added two columns to
the front of that section. I need the new columns to calculate in the
formula. The cells in question for the formula below would be C10 (time in)
and D10 (time out).


=IF($F$10($A55),IF($E$10$B55,0,IF($A55=$E$10,IF ($F$10<$B55,($F$10-$B55)*1440/60,0.25),IF($F$10$A55,($B55-$E$10)*1440/60))),0)+IF($H$10($A55),IF($G$10$B55,0,IF($A55= $G$10,IF($H$10<$B55,($H$10-$A55)*1440/60,0.25),IF($H$10$B55,($B55-$G$10)*1440/60))),0)+IF($J$10($A55),IF($I$10$B55,0,IF($A55= $I$10,IF($J$10<$B55,($J$10-$A55)*1440/60,0.25),IF($J$10$B55,($B55-$I$10)*1440/60))),0)

Any thoughts??? Let me know if you need more info if I am not clear.
Thanks!
