Menu dropdown stay always open

Deleting this line causes a syntax error.
Deleting the closing tag also, no syntax errors but then I have many other appearance and conflict issues

This is the code in this area

<script>
<script type="text/javascript" src=" ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js ">
<script type="text/javascript" src=" ajax.googleapis.com/ajax/libs/jqueryui/1.8.23/jquery-ui.min.js ">
<script type="text/javascript">
jQuery.noConflict();
</script>

It clear that HTML is incorrect:

<script>
<script type="text/javascript" src="ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>
<script type="text/javascript" src="ajax.googleapis.com/ajax/libs/jqueryui/1.8.23/jquery-ui.min.js"></script>
<script type="text/javascript">
jQuery.noConflict();
</script>

<script> should be removed, nothing else

OK. I removed this line.
Dropdown still expanded.

I ignored the error in code, and seems to work now.
