copying and pasting a formula

[Guest]

I have the formula "=A1*Z1." I would like to copy and paste this formula to
several cells starting with the first cell down. I would like the next cell
down to be "=A2*Z1" and the next one "=A3*Z1," etc. Instead what I get is
"=A2*Z2" and the next one "=A3*Z3," etc. Is there a way that I can copy and
paste this formula to a large amount of cells and and keep the second factor
"Z1" from changing?

Start with =A1*Z$1

=A1*$Z$1

The $ signs anchor the cell reference.

$Z1 anchors the column

Z$1 anchors the row

$Z$1 anchors row and column.

For more on this see Help on Absolute and Relative references.
