Really appreciate your help and so fast too! I used your formula in
and the table below is a sample of the spread sheet. Everything is
working except when the MOIST. column which is below 15.4 - it is 14.8
the DRY BU should be 974.29 just like the WET BU. Hope that made
sense.

NET WT MOIST. WET BU DRY BU
50540 18 902.50 875.80
52660 15.5 940.36 940.36
54560 14.8 974.29 0.26
