Google ads in footer

[nenemaria]

I want to add a google ads banner to the footer of my shop.
I presume I need to put the code in tpl_footer.php but where abouts do I put it?

The code for it is a small javascript, so do I just add the whole script into the tpl_footer.php?

<script type="text/javascript"><!--
google_ad_client = "pub-9233685764471005";
//728x90, created 01/12/07 - long across
google_ad_slot = "8042717951";
google_ad_width = 728;
google_ad_height = 90;
//--></script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

I presume it goes inbetween this somewhere? but I don't really know where!

<!--bof-navigation display -->
<!-- <div id="navSuppWrapper">
<div id="navSupp">
<ul>
<li><?php // echo '<a href="' . HTTP_SERVER . DIR_WS_CATALOG . '">'; ?><?php echo HEADER_TITLE_CATALOG; ?></a></li>
<?php if (EZPAGES_STATUS_FOOTER == '1' or (EZPAGES_STATUS_FOOTER == '2' and (strstr(EXCLUDE_ADMIN_IP_FOR_MAINTENANCE, $_SERVER['REMOTE_ADDR'])))) { ?>
<li><?php require($template->get_template_dir('tpl_ezpages_bar_footer.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_ezpages_bar_footer.php'); ?></li>

<?php } ?>
</ul>
</div>
</div>  --> 
<!--eof-navigation display -->

I currently have eveything else in the footer disabled except the copyright and powered by Zencart link.

Thank you in advance,

Maria.

Put your Google ad code in the footer using the banner manager - then you can turn it off or change it through the admin without touching any Zen Cart files.

Yes, I just tried that, but for some reason enabling the banner in the footer is causing a huge empty gap at the bottom of my page. I have the height of the page set to exactly 2000 px in the stylesheet, but the banner seems to change this.

Edit: Figured that out now, no problem.
Thanks for the help.
