First thing you'll want to do is include is a
lock command. Using MSG_FACE as you have is intended to only be used in scripts where the NPC only has a simple message to say.
Another common mistake beginners make is providing the incorrect person number to applymovement by mistakenly thinking 0x11 is the same as 11 in decimal, when the correct value for 11 in hex is 0xB (assuming you did indeed make such a mistake).
I've fixed the lock command for you.
