Can anyone help me with this problem?

When I use "Fill-Down" (ctrl-D) and "Fill-Right" (crtl-R) to fill formulas
into cells, I am getting the correct formulas, but the values are not correct.

Even though each formula has different cell numbers in it, the displayed
numbers in each of the filled-down-cells is identical to the first cell in
the fill down column. However, if I manually enter each formula (instead of
using "Fill-Down" (ctrl-D) or "Fill-Right" (crtl-R), ONLY THEN is each value
correct.

Also, when I change a value in a cell in a spreadsheet, any cells tied to
that cell in a formula DO NOT CHANGE.

I have tried reinstalling Excell 2003, but the problem persists.

CAN ANYONE HELP ?!?

Thank you
