Nothing I add to header will display AHHHHH!

[legion_diabolic]

Will someone PLEASE tell me what the %&THETD%^EUJ!! you have to do to have html code you've added to the header template actually work???!!!

I'm trying to display 3 random banners below the title image, I have separate php document that handles the banner rotation, so I tried a simple php_include directly below the title image:
<? include("ban-inc-smo-1.php"); ?>
Nothing.

I tried pasting the javascript code directly into the header template:
<table width="650" height="136" border="0" align="center" cellpadding="0" cellspacing="0">
<tr>
<td><div align="center">
<script type="text/javascript" src="ban1a.js"></script>
</div></td>
<td><div align="center">
<script type="text/javascript" src="ban1b.js"></script>
</div></td>
<td><div align="center">
<script type="text/javascript" src="ban1c.js"></script>
</div></td>
</tr>
</table>

NOTHING!

Nothing. I tried adding a simple stupid image link to the header template:
<p><img src="banners/120x60/temp/hosmd.gif" width="272" height="203" /></p>

NOTHING!!!

And for heavens sake, if ANYONE feels compelled to say "you need to have javascript turned on" will you PLEASE explain exactly, precisely, in detail what you mean by that and exactly where and how you "turn javascript on". Because it's not in the vbdocs, it's not found here by doing a search, and it's not in the admincp anywhere I have looked during the past 8 hours of pulling my hair out ove this stupid, idiotic, rediculous problem. HEEEEEEEEEEEELLLLLLLLLLLPPPPPP!
