calling javascript from template file

There is a spot above the two right sidebars reserved for ads and uses a template file called ads.php. I have one ad to put in that spot that unfortunately is in javascript and I just can’t get anything to appear. I have entered this in my header file right after the meta tags:

<script type=”text/javascript” src=”/ad1.js”></script>

and this is all that is in my ad.php file:

<div id=”ads”>
<script type=”text/javascript”>
<!–
ad1();
//–></script>
<img src=”<?php bloginfo(‘template_url’); ?>/images/ad.jpg” width=”125″ height=”125″ alt=”Your Ad Here” />
<img src=”<?php bloginfo(‘template_url’); ?>/images/ad.jpg” width=”125″ height=”125″ alt=”Your Ad Here” />
</div>

Is there help out there?
