Stop Iframe From Scrolling

So I have this Cakeslice code:

<div style="overflow: hidden; width: 390px; height: 157px; position: relative; margin:0 auto;" id="i_div">
<iframe name="i_frame" src="http://www.junkbusters.com/cgi-bin/privacy" style="border: 0pt none ; left: -8px; top: -215px; position: absolute; width: 1280px; height: 606px;" scrolling="no"></iframe></div></div>

When I view it in a browser, even though you can only see the portion that I cakesliced, if I hover my mouse over that portion, I'm able to scroll around in the iframe. Is there a way I can prevent this from happening (I want to disable the scrolling inside the iframe)?

overflow:hidden; might work, not sure.

Code:

Example:

<div style="overflow: hidden; width: 390px; height: 157px; position: relative; margin:0 auto;" id="i_div">

Change margin auto; -----> margin:0 disable;

This should fix it

Good job pleasures

Hey guys I tried all of your suggestions and I'm sorry to say nothing has worked for me. How is everyone doing this because people are iframing offers without scrolling enabled.
