function problem regarding cell range

[chindo]

I have a function that takes in a range of cells, but when I want to do
a fill (or hold down ctrl-d to copy the function over multiple cells in
the same column), the range of cells changes from A1:B9 to A2:B10, and
the next function will take in A3:B11 and so on. How do I stop this
automatic changing from occuring so that it only takes in A1:B9 in
every single cell?

You need to change your references to absolute: $A$1:$B$9. If you click the
cell with the first formula and highlight the cell references in the formula
bar, hitting function key F4 cycles between relative (A1), absolute ($A$1),
and the two mixed ($A1 and A$1) references.
Check Excel's help 'About cell and range references.'
