Help With Making a New Ability

I was trying to make a new ability with the same effect as the abilities Sharpness or Strong Jaw but for Two-turn moves. After defining two turn moves in the Battle_Move script, and adding the ability to the Battle Ability Effects script it doesn't work at all, just does the same amount of damage as if you were to normally use the move. I even added an echoIn statement at the end and it doesn't output anything into the console? Can someone help me out, is it that two-turn moves need additional script to active the damage boost?
