Including templates in VBulletin

[Sothside40]

Hey, I'm currently trying to write a mod (my first) for vBulletin, and from the mods I've read it seems like they've been able to include their templates inside of other templates such as:

<template name="myTemplate" etc="" etc="">
<div>This is what the first template is</div>
</template>

Then from there I go into the style editor, and inside of the footer template I throw in: $myTemplate. The desired result is for the template I defined as "myTemplate" to be shown inside of the footer. Am I mistaken on the functionality of this? And if so, can you please tell me what I've done wrong?
