question about wordpress

If i use
<script type=”text/javascript” src=”http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js”></script&gt;

my image carousel works but when i use
<script type=’text/javascript’ src=’path-to/content/wp-includes/js/jquery/jquery.js?ver=1.3.2′></script>
it doesn’t work and i get the error msg

$ is not a function
