[jQuery] Autosuggest breaks in ie7/8

Hello,

I got this code for search auto suggest and everything works fine in
Firefox, Chrome, Opera etc. But it breaks in internet explorer 7 and
8.

I get this error:
-----------------------------------------
Line: 158
Character: 2
Code: 0
Error Message: 'fghds' is null or not an object
URL: http://localhost.com/js/search.js
-----------------------------------------

This is the jquery script:

var SEARCH_BOX_DEFAULT_TEXT = 'Enter the keywords:';

var AJAX_PENDING_TIMER;
var CURRENT_PAGE = 1;
var CURRENT_LIMIT = 5;

function init() {

var sTextBox = $("#search_val");

sTextBox.focus(function() {
if(this.value == SEARCH_BOX_DEFAULT_TEXT) {
this.value = '';
}
});
sTextBox.blur(function() {
if(this.value == '') {
this.value = SEARCH_BOX_DEFAULT_TEXT;
}
});
sTextBox.blur();

sTextBox.keyup(function() {
var q = $("#search_val").val();
if( q == SEARCH_BOX_DEFAULT_TEXT || q == '' || q == undefined ||
q.length<=3) {
HideLiveSearch();
}
else {
clearTimeout(AJAX_PENDING_TIMER);
CURRENT_PAGE = 1;
AJAX_PENDING_TIMER = setTimeout("PerformLiveSearch()",300);
}

});

$("#livesearch_result_close_link").click(function() {
HideLiveSearch();
});

}

function NextPage(p) {

I'm really getting headache to debug this one. Could someone help?
