[jQuery] Jquery JQzoom is not a function error, why?


I am working on an ecommerce site that uses smarty tpl files and I am
having trouble implementing JQzoom, I have already use a java based
menu system so I am aware of the {literal}{/literal}
I am trying to use JQzoom for product images and when the product page
loads the java isn't working. Firefox error console says.
"Error: $(".jqzoom").jqzoom is not a function
Source File:/index.php?target=products&product_id=30472
Line: 23"
When I run firefox's javascript debugger, jquery.jqzoom1.0.1.js is
there and the.jqzoom function is present
NB, this isn't working in explorer either
Here is my code
<head>
{include file="meta.tpl"}
{if $content == "product_details" || $content == "products"}
<link rel="stylesheet" type="text/css" href="{$skin_dir}/jqzoom.css" /
