If the cell that contains the formula was formatted as text, you'll see only
the text of the formula, as you are describing.
Simply changing the format to "General" *will not* work.
After changing the cell format, you have to edit the cell in order to have
it revert back to a calculating formula.
Try this:
Click in the "bad" cell, then
<Ctrl> <Shift> <~>, then
<F2> <Enter>.
If that works, you know that the cell format was "Text".
Some other possibilities might be a "space" in front of the equal sign,
Or, the entire sheet could have been set to display formulas.
You can toggle this setting off and on by,
<Ctrl> <~>.

Thanks for the quick reply
No I didn't do anything like that. If I copy the cells to another
sheet the functions will work.
