I have an equation column ("Cost Sum") in a custom made bill of materials.  It multiplies quantity by cost.  Any idea why it isn't showing the decimal places (Like the cost does)?

(See Image 1 and 2).

Also, if I add a comma to my cost value in my part configuration, it doesn't display in my equation column ("Cost Sum").. Instead it shows a 0.

(See "1000.00" text in Image 3 and 4).
