    Multiplication/addition function

    I obviously know less about functions than I thought I did. I've got the attached spreadsheet set up except getting totals at the bottom. The production total L44, would be column A multiplied by the quantity entered in columns L and summed. Same for Total SF, square footage in column B times quantity in L and summed at the bottom. This would continue daily, needing sums under each column. I had a real mess going... Any help would be appreciated.

    Try:

    =SUMPRODUCT(B3:B41,L3:L41)

    and

    =SUMPRODUCT(A3:A41,L3:L41)

    respectively in L43 and L44
    Where there is a will there are many ways.

    In L43 use this array formula, use CTRL+SHIFT+ENTER to comit formula.

    =SUM(B3:B41*L3:L41)

    L44 would be
    =SUM(A3:A41*L3:L41)

    When done correctly curly brackets { } will be added to the formula to denote they are array formula.

    The Sumproduct() formulas yield same result and without having to confirm with CSE keys...and it uses the most basic form of the native Excel Sumproduct() function.
