Script malfunctioning to autosize iframe - Help needed

[Joep]

Hello everyone,

I encountered a problem while trying to create a sitepage with a dropdown menu and an iframe.
The options in the menu must load in the iframe.
I need the iframe in this page to resize it's height to the size of the page that loads in it.
The current 3 pages that have to load in the iframe all have different heights.
Hopefully someone can help me with this.

This is the html :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>My Website</title>

<script type="text/javascript">
function SetIFrame()
{
myFrm = document.getElementById('myIFrame');
myFrm.src = document.mapform.jump.options[document.mapform.jump.selectedIndex].value;
}
</script>

<script>
function alertsize(pixels){
pixels+=32;
document.getElementById('myIFrame').style.height=pixels+"px";
}
</script>

</head>
<body bgcolor="#FFFFFF" text="#5C5457" link="000000" vlink="000000" alink="000000">
<div align="center">
<table width="70%" border="1" bordercolor="#333333">
<tr>
<td>
<div align="center">
<br />
<br />
<form name="mapform" method="post">
<p>
<br />
<select name="jump" size="1">
<option value="http://www.mydomain.com/products1.html">Products part 1</option>
<option value="http://www.mydomain.com/products2.html">Products part 2</option>
<option value="http://www.mydomain.com/products3.html">Products part 3</option>
<option value="" selected="selected">select</option>
</select>
<input type=button onclick="SetIFrame()" value="Go" />
</p>
</form>
<div align="center">
<iframe id="myIFrame" name="Frame1" width="1045" src="http://www.mydomain.com/main.html" frameborder="0" scrolling="no" body onload="parent.alertsize(document.body.scrollHeight);"></iframe>
</div>
<br />
</div>
</td>
</tr>
</table>
</div>
</body>
</html>

Can anyone please help me solve this?
Thanks a lot in advance for your help!

Um why are you using an iFrame instead of a div?

What are you trying to do?

You want the iframe to inherit the height of the page it's opening, have you thought about implementing it some other way? Are you trying to display external websites?

Problem solved.
I contacted a guy on Fiverr and for 5 bucks he made me the page (using div instead of iframe).
Thanks for your help.
