3 tables hold money value but they are inputed into
the database without the dollar symbol (without $).
So the value could be 3.00 etc...
I want to calculate by adding (+) them together. A
username is in each table. So only the username
matching in each table must calculate. So if in table
1 username Chris has 3.00 and in table 2 Chris has
5.00 we need to add the two together.
If you value equals 0 or NULL or blank it should
either a) ignore it or b) add it as a zero.
