Textbox value is being strange (Value then undefined)

[tomharto]

If i run this section of my code

alert($("#issueBox").val());
$("#mainBody").html("Loading…");
var Link = $(this).attr("href");
var Issue = $("#issueBox").val();
var Rel = $(this).attr("rel");
alert(Issue);

The first alert box displays the correct value yet the second one displays undefined. It will be some stupid simple thing i cant see but i can anyone else tell why its being weird?

EDIT: Found it, the textarea was inside mainBody and that was getting replaced by the Loading message.

Change it to this and it worked

 $(".replyer").click(function(event){
						event.preventDefault();						
						var Link = $(this).attr("href");
						var Issue = $("#issueBox").val();
						var Rel = $(this).attr("rel");
						$("#mainBody").html("Loading…");
						$.ajax({
		    				type: "POST",
			   				url: "pages/"+Link,
		    				data: Rel+"&issue="+Issue,
		    				success: function(msg){
								$("#mainBody").html(msg);
							}
						});
					});
