Excel 2010 Page Setup greyed out

[henway]

I have a printer installed and Ready.
I have tried changing to all different views (Normal, Page Layout, Page Break) before going to File > Print > Page Setup.
I have tried selecting one cell (and hitting esc a few times) and I have tried highlighting the entire sheet.
The worksheet isn't protected nor is it shared.

Every time I go to the Page Setup, Sheet tab, the following are all greyed out:
Print Area, Rows to Repeat at Top, Columns to Repeat at Left.
All other functionality in the Page Setup is unaffected.

Any idea of what I'm missing to be able to allow it to repeat rows at the top?

Try

Page Layout ribbon tab|Page Setup group
