cut and paste your exact macro in here and i'll let you know what's wrong.

My macro was just off the top of my head it's best if you click the spell out of your spell book and then get rid of the (Rank 2) another problem with having modifires is when wow has them mapped to something else.

Do this: if you are trying to use f5 go into your key settings or bongos etc and bind F5 Alt+F5 Shift+F5 Ctrl+F5 and then unbind it. this makes sure that ctrl+F5 is not bound to something that you don't see like pet bar key 5 or secondary set key 5.
