flash button linking not working??

[cagalindo]

I created a flash button and I saved as .SWF and put it on my template in dreamweaver. Now my template has an iframe.

The iframe name is set to "content". And the flash button target is set to open in "content".


Here is the flash button code:
this.onRelease = function() {
getURL("portfolio.htm", "content");
}

Here is the template iframe code:
<iframe src="home.htm" name="content" ID="content" width="100%" height="100%" marginheight="0" marginwidth="0" frameborder="0" scrolling="auto" border="0">I-frame</iframe>

I just don't understand why it is still opening the link in a new browser, and NOT in the iframe.
Any ideas?

oh, and I am including the full template and flash button codes if anyone needs them...

thanks in advanced
