A problem with Costum Module, please help! Options

[Princess_Chen]

I was trying to put an extra module on my xanga but everytime I click preview, nothing changes, I see no costum module.

Please help me!
Here is the code I used

CODE

<!-- begin code provided by createblog.com -->
<script>
titleContent = '::New Year's Resolutions::';
moduleContent = '[x]Eat less
[x]Exercise more
[x]Be more responsible
[x]Learn how to save!
[x]Start a diary
[x]Be more sociable
[x]Less computer usage
[x]Stick to Resolutions!!! ';
sub = subTitle.parentNode.parentNode.parentNode.parentNode.parentNode
sub.insertAdjacentHTML('beforeBegin','<table border="1" cellspacing="0" cellpadding="4" width="100%" class="left"><tr><th valign="top" align="left" class="left">' + titleContent + '</th></tr><tr><td valign="top" class="left">' + moduleContent)
sub.insertAdjacentHTML('beforeBegin','<BR>');
</script>
<!-- end code provided by createblog.com -->

Can anyone tell me what Im doing wrong?!
BTW...If you're wondering where I placed the code, I placed it on my website stats.
