A pivot table may be an easy solution for you. Make Item_Num, Day, and Time
row fields. Make count of item # a data field. The resulting pivot table
will show all the uunique Item_Num/Day/Time combinations and the # of times
they exist in your list.

You could also try selecting your entire range and then choose from the
Excel menu path Data / Filter / Advanced Filter. And then choose Unique
Reocords Only and choose Okay.

I'm trying to count the unique values given several conditions, for example
in the example below, count the number of unique Item_num's that were sold on
Wed during the Morning, which would return 2:

A B C
1: Item_Num Day Time
2: 1 Wed Morning
3: 1 Wed Morning
4: 2 Thur Evening
5: 2 Thur Evening
6: 3 Thur Morning
7: 3 Thur Morning
8: 4 Wed Evening
9: 4 Fri Evening
10: 5 Wed Morning
11: 5 Wed Morning
