I have two worksheets.
The first is a list of Pipes and specifications
ColA           Col B              Col C           Col D
Schedule    Diameter        Volume        Weight
10                 .5                  .2                  1
10                  1                  .3                   6
40                  .5                 .5                  4
40                  2                  .3                  2
80                  3                  2                   10
80                  10                 10                 25

The second is a list of different pipes with different products running thru
them.  I know the schedule of the pipe and the diameter.  I need to look at
the schedule and pipe size on the first sheet and report the volume on the
second one.
How do I do this?

Thanks
