What is wrong with my syntax?

I have looked, compared, and tried several variations, but I keep getting "syntax error" or "trigger not recognized".

// =========== REJOINED AFTER KICKED OUT =====================
// This series of exchanges describes rejoining the party after being kicked out.

IF ~Global("zkwHughBooted","LOCALS",1)~ THEN BEGIN CameBack
SAY ~Hi! Have you changed your mind?~
IF ~~ THEN REPLY ~Yes. We have had a change of heart. We would like you to join our party.~ GOTO Rejoined
IF ~~ THEN REPLY ~Yeah, but I still don't want you in the party.~ GOTO RefusedAgain
END
