Greetings all. I have column A "Product", column B "Quantity", and I want
to
add column C "Total Cost", all with data starting at row 5. I want to
choose
cell C1 and enter in a dollar amount. Then I want to format C5:C10000 to
be
equal to the value in column B multiplied by the dollar amount in C1. I
tried to do the formula for C5=B5*C1 then drag it down. What happens is
that
when I drag it down to row 6 the formula becomes C6=B6*C2 and so forth. I
need to be able to make C1 stay constant for the entire column. Thank you
in
advance.
