SUMPRODUCT Help
 

Please help me write a SUMPRODUCT formula
I have 3 columns
A=arrival time
C=time 1
D=time 2
I would like column B to show a count of how many times Col A falls between
each C & D pair
Thank-you
Zb

SUMPRODUCT Help
 

Assuming start times in col C, end times in col D
In B1: =SUMPRODUCT((A$1:A$100=C1)*(A$1:A$100<=D1))
Copy down to the extent of paired times in cols C and D. Adapt the range in
col A to suit beforehand.

I tried this but it It still is not giving me what I need. I'm tring to
count how many people are waiting whenever someone new arrives. I need to
compare each time in col A (Arrival) agaist each pair of times in cols b&c
and count the times that a falls between them. Thank-you Zb

Think what was suggested earlier was as per your intents and should have
worked. Perhaps you might want to check your data in cols A, C and D for
consistency. These should all be real times.

If it's not a data prob, could you copy n paste some actual sample data &
the expected results in plain text, in response here?

A further thought ..
Assuming start times in col C, end times in col D
In B1: =SUMPRODUCT((A$1:A$100=C1)*(A$1:A$100<=D1))

Above presumes the start and end times in cols C and D are non-overlapping.

If they are overlapping, eg if in C1:D2 you have:

7:00 AM 8:00 AM
8:00 AM 9:00 AM
etc

just adjust the upper limit, viz use instead in B1:
=SUMPRODUCT((A$1:A$100=C1)*(A$1:A$100<D1))

Max This is working only not quite the way I was hoping the # waiting colunm
should show of those that were currently in waiting status as each
individulal arrives.
Thank you for your time and help w/ this. i was thinking sum products but
maybe there is another way to do this. I'm open to suggestions.

I did a copy an paste of a csv for an example

I'm not sure how you arrived at the figs in the "#waiting" col.

Anyway here's some thoughts expressed/illustrated in this sample:
http://www.savefile.com/files/991574
Waiting Line Counts.xls

2 scenarios are given:
1. With col C (Start_wait) as-is
2. With col C filled down, using Sub FillColBlanks() by Dave Peterson**

For each scenario, the formula placed in B2, copied down is:
=IF(OR(C2="",D2=""),"",SUMPRODUCT((A$2:A$100=C2)* (A$2:A$100<=D2)*(A$2:A$100<"")))

Hope one of the 2 scenarios brings you closer to your intents ..

**See Debra Dalgleish's:
