Roughly, yes. But I do not want a pick list like you have there on the right. I would rather use a dropdown list that is populated from the minerals table.
And then a calculation on the form that calculates the mineral cost times the number of rocks found in that claim.
I am making a simple db to track mining for an online game (no not WoW), another one.
Anyway, I have 2 tables.
tbl_Minerals: Which has these 2 fields:
MineralName (text field)
stoneValue: (currency field)
So it looks like this:
tbl_Minerals:
MineralName stoneValue
Mineral1 $0.01
Mineral2...
