Commission based On product sold

hi
i need assistance of this code i dont know where an wrong

Inventory Cost Report:1, 1, 1, 1, 1]

Item|Unit|Inv|Cost|Price|Total
{REPORT CONSUMPTION DETAILS:C.Name,C.Unit,C.Inventory, C.Cost,C.Price, ([C.Inventory][C.Cost][C.Price])}
Totals||{REPORT CONSUMPTION DETAILS:C.Inventory.sum, C.Cost.sum,C.Price.sum, [([C.Cost]*[C.Inventory]).sum]}

Whats this meant to be… its not valid as far as I can see. Guessing your missing * or /
Similar with your total line I would imagine. dont think you can tack .sum on the end of a calculation like that.

Already i have * or / between [C.Inventory] [C.Cost] [C.Price]

steal no showing

Make sure you highlight and click < / > button on forum post editor to show its code and prevent any html stripping etc.
If you already have you * then I would ask why the ( ) brackets? Where have you seen that?

{REPORT CONSUMPTION DETAILS:C.Name,C.Unit,C.Inventory, C.Cost,C.Price,[C.Inventory]*[C.Cost]*[C.Price]}

What is that calculating? Cant understand the use of cost multiplied by price

i want to add a column to show selling price on this
