need some help with script

i currently run a PC hardware & acessory reviews site, im trying to display 2 advertising blocks using simple javascript that i picked up from 2 sites.
Im only just getting to grips with phpnuke and coding - but thses 2 blocks looked really simple.
1. copy the code
2 paste it to the place on your page you want Tracker to appear
Simple eh?
i created a new block inserting the copied code - that didnt work - just wouldnt accpet the block.
i then pasted all the html code into notepad and uploaded to the blocks section of my site naming it block-tracker.php
i then created the block & the advert showed up BUT with one slight snag, underneath the advert it showed another small block saying:
there isnt any content for this block right now.
How do i get rid of this other block? it happens when doing both blocks.
is there some extra piece of code i should be adding to the php file?

check out my site and you will see what i mean:
URL

here is the code to the script:
<!-- begin AC Tracker code -->
<script LANGUAGE="JavaScript">
<!--
// Tracker customization parameters
// Do NOT remove anything below this line. Just change the values.
BGColor1 = "Black";
BGColor2 = "Gray";
BGColor3 = "Silver";
TextColorHeading = "Red";
TextColorCategory = "White";
TextColorArticle = "Blue";
TextColorDate = "Red";
TextFont = "Arial";
TableWidth = "150";
//-->

You got the wrong forum : this one is for java. If you want some help, try the javascript forum which you can find on this website too.
