Excel 2002

If I set up an area, say c1:c5, all locked and then Allow users to edit
range and protect worksheet, I would expect an allowed user to be able
to double click on any cell in the range and input in it or move to one
of the allowed cells and input to it.

This isn't happening, double clicking on anywhere in the range defaults
to the first cell and you can only input there, doesn't seem to be any
way of moving to the other cells.

What am I doing wrong? ;-)
