Lookup Hours from table based on date range...
 

Thanks in advance!

Basics:
- large raw data table w/ 2 date fields (start & end) amongst lots of
other data
- there's a field that totals the time for process from start
to end
- there's also a field with an equipment number for that line
item

- 2nd large data table w/ engineering/offline time information for
each piece of equipment for each day (hours per equip# per date)

I need to come up with a formula or macro to take out the
engineering/offline time from the process time for each line item in
the large raw data table.

Ex: start = 1/1/2006 00:00 ; end = 1/5/2006 00:00 ; total = 96:00
hours
engineering/offline : 1/1/2006 = 12 hours ; 1/2/2006 = 6 hours ;
1/3/2006 = 6 hours ; 1/4/2006 = 12 hours Total = 36 hours

I need to be able show that for this line item in the raw data
table that the applicable time is 60 hours (96 - 36).


I'm stumped!


thanks again.
