clearing xml object or traversing fix needed

clearing xml object or traversing fix needed

The code below works fine except the xml code returned by 'data' doesn't seem to reset itself with clicks on new lines. If I alert out the value of "snip_content" it DOES change with new clicks, but the inserted text in the insertAtCaret() function does not change...it always shows the first value of snip_content from the first click. It feels to me kinda like the xlm is being appended or somewhere else a var is not being reset. I've tried resetting with every function and re assignment I can think of to no avail. Help greatly appreciated.

$(".snips"). //find snips
click(
function() {
$('.snip_tip').empty(); //clear out existing snip tips
var my_snip = $(this); //identify the snip clicked on
var my_id = parseInt($(this).text()); //extract the snip_id from the text

$(".snips").css("background-color","white"); //reset highlighting to white
$(my_snip).css({"background-color":"lightgreen"}); //highlight the snip we're describing
$.post("index.php?action=snip_service", {"id" : my_id}, function(data) { //ajax call to snip service
$(data).find('snip').each(function() { //xml dom find your snip

var description = $(this).find('description').text(); //find the description attribute
var snip_content = $(this).find('text').text(); //get the snip_text content
var html = '<span class="snip_tip"> - ' + description + '</span>'; //make the text
$(my_snip).append(html); //add html snippet to end of snip line

//make snip draggable/droppable
$(my_snip).draggable({
helper : "clone"
});
$("#letter_body").droppable({
accept : ".snips",
drop : function(ev,ui) {
$(this).insertAtCaret(snip_content); //call insert function to put snip content in at cursor
}
});
});
}, "xml");
}
);
