My code using Sum function with the - operator.

     What is wrong with my code?   [Apply Discount] is a checkbox  the rest are numeric formula fields.  [Discount] is a numeric field.  It will Sum but fails to subtract the [Discount] even when not used in the IF statement. 

    If([Apply Discount]= true, Sum ([SoftScape Total],[HardScape Total],[Aggregate Total],[Removal Total]-[Discount]),Sum([SoftScape Total],[HardScape Total],[Aggregate Total],[Removal Total]))

    Hi Billy,

    Have you tried wrapping just the section with the subtraction in its own set of parenthesis?

    If([Apply Discount]= true, Sum ([SoftScape Total],[HardScape Total],[Aggregate Total],([Removal Total]-[Discount])),Sum([SoftScape Total],[HardScape Total],[Aggregate Total],[Removal Total]))

    Just to make sure that Subtraction is being calculated first.

    Let me give it a shot.

    It still doesn't do the subtraction.  I get the sum total whether Apply discount is checked or not.

    Billy,
    Is the discount a dollar amount number or a %?

    Good idea though, Here is the code that worked.    What you said made me think.  

    If([Apply Discount]= true, Sum ([SoftScape Total],[HardScape Total],[Aggregate Total],[Removal Total])-([Discount]),Sum([SoftScape Total],[HardScape Total],[Aggregate Total],[Removal Total]))

    Nice I'm glad to hear that worked

    It is a dollar amount.

    Could you try putting in 1 instead of true for your checkbox really quick and see what you get back?

    So [Apply Discount]=1

    The code I posted above worked.  Just the subtraction part needed to be in its own set of parentheses.

    The parens around the subtraction value aren't relevant, it's that you needed to do the subtraction outside the arguments for Sum().

    In other words your final code
    Sum ([SoftScape Total],[HardScape Total],[Aggregate Total],[Removal Total])-([Discount])
    works, and this would also work
    Sum ([SoftScape Total],[HardScape Total],[Aggregate Total],[Removal Total])-[Discount]

    I don't know offhand if
    Sum ([SoftScape Total],[HardScape Total],[Aggregate Total],[Removal Total],-[Discount])
    would work, but I suspect not

    Addendum - if for some reason you HAD to do it that way (no idea why you might, just go with it), you'd either put negative values in [Discount] or else create a field (called [Discount to Apply] or something) with a formula [Discount]*(-1) and use that in your sum formula:
    Sum ([SoftScape Total],[HardScape Total],[Aggregate Total],[Removal Total],[Discount to Apply])
