When looking at an array of numbers
0 0 0 1 1 2 2 2 2 3 3 3 3 3 3 2 2 2 1 1 0 0 0 0 0
Each corresponding in a column under a time (ie in this example the array starts at 630 am and goes by 15 minute intervals to 9am then goes from 3pm to 6pm in 15 minute intervals - so at 715 and we go need 1 teacher, at 745am we need 2 teachers and at 845 we need three teachers.
I need to be able to have excel look at the full array and send me data back like:
715am - 1 teacher
745am - 2 teachers
845am - 3 teachers
415pm - 2 teachers
500pm - 1 teacher
530PM - 0 teachers
can you help me??>

I think I would be inclined to do this with the MATCH function - AS LONG as you know the maximum number of teachers you are going to need
With 1 stored in cell A4, and with the data in A1:X2 (in my working example) the formula in B4 would be
This function will work for the increasing number of teachers - for the decreasing amount you would need to offset the data - so
where row 6 contains the maximum number of teachers used.
These cells return the column number of the time, so by using the INDEX function you can get the time that this equates to
I hope that this makes sense - do let me know if I can help further.
