NO she says "your compass that you barterd from me cant lead you to the chest?"
Jack - "maybe why?"
"AYEE Jack sparrow does not know what he WANT..or DO KNOW but are loath (AFRAID) to claim it as your own)
meaning its not the ****ing CHEST he's after
and If iJack's arc is not gaining Elizabeth then why the flying **** did Ted Elliot the WRITER of the movie say THIS:
Box Office Mojo: What is the meaning of the series?
Ted Elliott: It's a study of what is a pirate. How free can you really be? What are those trade-offs? Jack kind of represents the ultimate free man? he really has no obligations to anybody, and, obviously, if you make an obligation to somebody, you're limiting your own freedom. But, if you're not willing to limit your own freedom, you can't have those relationships. If you look at Pirates of the Caribbean: Dead Man's Chest from that point of view, you kind of see what really leads to Jack's ultimate fate and why Elizabeth does what she does.
AND THIS:
"The reason we included the "Why is the rum always gone?" line was not just as a callback to the first movie; it was intended to remind audiences of the specific circumstances that it referenced, and so act as a cue to what Jack had on his mind: the woman who he was first attracted to and then infuriated with (or: the woman who Jack never would have been infuriated with if he had not been attracted to).
So, the deal with compass: Jack simultaneously wanted Elizabeth and wanted to be as far from Elizabeth as possible. Whichever of those he wanted most would cause him to immediately want the other more ... so the compass would not settle, swinging between "Port Royal" and "antipode of Port Royal" (which is sort-of-but-not-quite Singapore, btw).
(There was much debate about whether, in the first scene aboard the Pearl, to show the compass pointing in a specific direction and have Jack set course in the opposite direction, or to show it as it is in the movie. I think the first would have made it more clear to the audience that something weird was going on with Jack ("he's not going where the compass points? What's up with that?"

, but the second is actually more demonstrative of his emotional state)(at least, that was the theory)."
