My request sounds simple, but I have yet been unable to do it.

I have a worksheet with a column that has a shipment id, say "H-5"
I also have another column that lists the number of samples in that
shipment, say 3.

I need something that will create two new columns, one with the shipment id
and the other with the sample number. So based on the above entry it would
create three rows:
A B
1 H-5 1
2 H-5 2
3 H-5 3

Since there were three samples, it created three entries for each sample and
then would continue on for each entry on the original worksheet, say H-6,
five samples.

Any suggestions would be greatly appreciated.
Thanks,
-Derek
