[jQuery] Cross-browser problem

[jQuery] Cross-browser problem


Hello everyone! I wrote this script and it doesn't work in IE6 & IE7
and Chrome, but works in last Firefox and last Opera. In IE it simply
doesn't list <option></option> at all and doesn't react on current_cat
variables at all.
If i set all "current" variables to 0 it shows all data, but doesn't
react on <option> click event.
Firebug doesn't show any problems, tried to check all values with -
console.log(); and they all contain proper values as it seems.
Please help me to find a problem.
console.log(current_cat1,current_cat2,current_cat3);
null1 null2 null3
0 null2 null3
0 0 null3
0 0 0
var current_cat1 = 'null1';
var current_cat2 = 'null2';
var current_cat3 = 'null3';
function call_cats() {
    fill_cat1();
    fill_cat2();
    fill_cat3();
}
function fill_cat1() {
    $('#cat1').html('');
    var selected = '';
    var cat1 = $('#cat1');
    cat1.prepend('<option id="null1" value="null1"></option>');
        var i = 0;
        while(i <= main_cats['main_cat_rows'] - 1) {
            if(current_cat1 == 'null1') {
            $('#null1', cat1).remove();
            cat1.prepend('<option id="null1" value="null1" selected></
option>');
            current_cat2 = 'null2';current_cat3 = 'null3';
            }
            if(current_cat1 == i){var selected = 'selected';
            cat1.append('<option ' + selected + ' value="' + i + '">' +
