(Jquery Validate) Keep getting an error in IE8

Hi

I don't know what is going but my jquery validate plugin(1.5.5) is not
working and I am not sure for how long since I do most of my testing
on firefox.

The problem is this I go to one of my forms that jquery validate on it
and hit my "create" button my validation kicks in as it should and
does this right in all browsers including IE8. Now where it does not
work is when I do this.

I choose the first dropdown list and choose something. Then hit
"create" now all validation errors should show up expect the one for
the first dropdown box.

It does this in all browsers except in IE 8. I get this

This is what is on line 890

return options.length > 0 && ( element.type == "select-multiple"

| ($.browser.msie && !(options[0].attributes['value'].specified) ?
options[0].text : options[0].value).length > 0);

This like the whole method block.

methods: {

// http://docs.jquery.com/Plugins/Validation/Methods/required
required: function(value, element, param) {
// check if dependency is met
if ( !this.depend(param, element) )
return "dependency-mismatch";
switch( element.nodeName.toLowerCase() ) {
case 'select':
var options = $("option:selected", element);
return options.length > 0 && ( element.type == "select-multiple"

| ($.browser.msie && !(options[0].attributes['value'].specified) ?
options[0].text : options[0].value).length > 0);

case 'input':
if ( this.checkable(element) )
return this.getLength(value, element) > 0;
default:
return $.trim(value).length > 0;
}
},


Not sure what is going on.
