The first question is what are you intending the SUM function to do in each
of your formulae?
In what way do you want =SUM(C4*0.5) to differ from =C4*0.5 ?
In what way do you want =SUM(E4*15) to differ from =E4*15 ?
In what way do you want =SUM(G4+F4+D4) to differ from =G4+F4+D4 ?
In what way do you want =SUM(I4-H4) to differ from =I4-H4 ?
If you don't understand what the SUM function does, try looking it up in
Excel help.
If you want to fill the formulae down a column, look at the topic "fill" in
Excel help.
