BM Macro Setup

Hey guys. sorry for the nooby question but havent used gnomesequencer since they updated it to enhanced. i see in the sequence viewer in game the list of all the different class and spec macros etc. but after finding one i liked i went to the normal blizz macro area and created a blank macro with the same name as the one i like in the sequence viewer and left it blank like you used to do with OG gnome sequencer. Cant get anything to work. What am i doin wrong here? would love some help.
