Some help needed please.

I have a cell that is usually left empty, and as such a different cell returns the result (lets say) "default wording" However, on occasions I type something different in the first cell, (lets say) "
anything". In that case I want I want the second cell to produce the same word as typed in the first cell.
Here is my code in the second cell. Unfortunately it doesnt work. Can you tell me how to improve it?
Code:
=IF(cellwhatever="",default wording,IF(cellwhatever="anything",anything,))
