I have Office - Student and Teacher Edition 2003

I am having trouble making a table ...

I try to make a Data Table and try to
define $E$3:$G$16 as the range in the row input cell area so I can make
this a one-input data table

and then I enter C$9$ for the column cell input area



a pop up pops up saying that the input (row) cell reference is invalid

I hope this not a bug that can only be fixed if you have the full version of
the software

any clues?
