Hello all.

Now I need to figure up the "Net" dollar figure on frmLogs.  The gross is done.

To figure out the net:
Multiply the Gross (already calculated and shown in frmLogs) by either 50% or 60%.  

To figure out whether to use 50% or 60%.
I added to tblGrades a column called NetPerc (net percentage).  Each tree species has either a value of .5 or .6.  Now I need to look up that value to multiply to the Gross figure.

I can get this to work.
In frmLogs for Net, if I put this in the expression builder "=[txtGross]*.5" that works correctly.  

A couple things I tried.
I cannot get something like this to work: "=[txtGross]*[tblGrades]![NetPerc]".  Maybe I would guess I need to somehow add whatever the syntax to it something like this: =[txtGross]*[tblGrades]![NetPerc] WHERE tblGrades.Species = Species.  IDK.
