X-Cart forums - iFrame and xcart code

I am using an iframe to create a custum scroll bar. But I would like to pull my cat list. (i am hand entering the list right now :( )

http://www.dejaun.com/store/home.php?cat=13

If I use <iframe src="skin1/customer/main/scrollmenu.tpl">, I get the source code and no function.

so I am using this <iframe src="skin1/customer/main/scrollmenu.html" >, but get no ability to use xcart code

I want to inclue this, I believe:

Code:

{section name=cat_num loop=$subcategories}

{if $subcategories[cat_num].category}{assign var="tmp" value="1"}{/if}

{/section}



{if $subcategories}

{foreach from=$subcategories item=subcat}

{ $subcat.category|escape }

{/foreach}

{/if}

Many thanks.
