Making a Command cast a single spell

Hi everyone I'm new to FF6 hacking and I want to make a command that casts a spell similar to what the health and shock commands do. I made it so Control casts my spell but when a character uses it they: 
Walk forward, Walk forward again, Do the spell, and then not walk all the back.
I based the code on this thread (specifically C-Dude's first post) 

Is the double walk forward a bug or a specific issue with the spell I'm casting, If not is there anyway to fix it.
