Postioning Divs Question Options

[bah]

Alright, Im positioning my divs on this layout:

Here's the code, so far.

<center>

</center>

<div style="overflow:auto; width:400px; height:550px; margin-top:-350px;
margin-left:-1px;">
<style type=text/css>
/* remove regular modules */
table.footer, texttable.left, td.mainleft, table.left, table.navigation, table.search{display:none}
table.blogbody tr td {width:0px; padding: 0px;}
</style>

And yes, I've ended my div in the Website stats.

Here's my problem:
It only allows me to edit margin left in negative pixels. The problem is, I've made it to -1, and I haven't aligned it as far to the left as I would like it to be. If you look at it right now, the text is as far left as I can get it to go.
If I try aligning it in postive numbers, it just doesn't move from it's current position.
I tried setting the alignment to left, then postioning it, and it let me do that in positive numbers, and it worked, and I got it to the right place. However, the ad got moved to the left, and it was just bugging me.
So can someone either expain why its only aligning in negative numbers, and what I can do to fix that. Or, how to align the ad into the center when I have th alignment set at left.

Thanks a bunch!

Try the code below, I added position absolute to your div; try using negative or positive numbers now.

<div style="position: absolute; overflow:auto; width:400px; height:550px; margin-top:-350px;
margin-left:-1px;">
<style type=text/css>
/* remove regular modules */
table.footer, texttable.left, td.mainleft, table.left, table.navigation, table.search{display:none}
table.blogbody tr td {width:0px; padding: 0px;}
</style>

Try not closing your div in webstats. Just leave it open.
