problem with resize script, but why?

[KcDwayne]

I'm not sure why this isn't working, because the values are coming through.
[thecode]

checkParent = function() {
childHeight = window.frames['iframe'].document.getElementById("wrap").offsetHeight;
parentHeight = document.getElementById("subbody").style.height;
iframeHeight = document.getElementById("iframe").style.height;
parentHeight = ((childHeight + 5) + "px");
iframeHeight = (childHeight + "px");
}

[/thecode]

It reads (on the test page) the wrap height is 325px, and the iframe height is 150px. It should see that 'wrap' is 325 pixels tall, then add 5 pixels. Then take that number (330) and make the iframe and subbody elements heights.

Any idea why it isn't working?

parentHeight and iframeHeight are variables. Setting their value has no effect on anything else.
