I dont really know coding much but shouldnt it be
PHP Code:
new powerDown[10], powerUp[10]
formatex(powerDown, charsmax(powerDown), "+ability")
formatex(powerUp, charsmax(powerUp), "-ability")
register_clcmd(powerDown, "powerKeyDown")
register_clcmd(powerUp, "powerKeyUp")
Not sure about that at all tho. Or is that the same as you did?
Good luck.
