Open / close iframe problem

[PJJames]

Hi - first post so be kind!

I have a function that shows/hides an iframe. I actually found the function on this site. Here is the structure:

Mainpage:

Has a link which opens a floating iframe.

<a href="#" onclick="HideFrameComingSoon()">Click Here</a>

<iframe id="comingsoon" allowtransparency="true" style="display:none;" scrolling="no" src="comingsoon/soon1a.php"></iframe>
<script language="javascript">
<!--
function HideFrameComingSoon() {
var fr = document.getElementById ("comingsoon");
if(fr.style.display=="none") {
fr.style.display="block";
}
else {
fr.style.display="none";
}
}
-->
</script>

iframe :

<a href="" onClick="parent.HideFrameComingSoon()">Close</a>

This is working great - except when you've opened/hidden the iframe in IE7 and then click to re-open the iframe on the main page you get a 404. Works perfectly in Firefox.

I think it has something to do with the fact that the iframe loads a page within the /comingsoon directory and therefore IE get's confused, but I can't be sure?

Any ideas?

Hmm, I'm not a fan of frames.

I can't see the problem. Your aim is to open an iframe when link is clicked, then the iframe contains a link which closes the iframe? Well I tried it and it works for me in both Firefox and IE, so I'm guessing the problem lies with the comingsoon directory or something, but I'm clueless on how to solve that.

Thanks for giving it a go. Just to make it clear, the iframe opens (via the main link), closes(via the iframe link), then wont open again (via the main link).

Well, it does in Firefox but not in IE7.
