Bert,
Just getting caught up reading this thread!!!!

Here is the link Carl put for you of the screen shot I put in here:

UOM

As you can see that was page 147, I don't remember how long the actual list was but I do remember it was 147pages worth of acceptable UOM's.

I will try to find that info again and post a link, but it wasn't very helpful just said, you can't use these anymore!
