are 2 scripts possible?

are 2 scripts possible?

I'm brand new to JQuery, but I'm already stuck.
I have existing code within this:
<script language="javascript">...</script>

I tried adding this:
<script type="text/javascript" src="../../js/jquery-1.8.2.min.js">
    $(document).ready(function() {
        alert("got here");
    });
</script>

I'm expecting an alert when the page loads, but nothing appears.
