Flash button loading iframe content

OK, I surrender. I’ve searched about twenty threads, tried the advice that’s helped others, but I’m still having the following problem:

Using a flash button on an html page to load targeted content into an iframe on the same page without reloading the whole html page (I know, “groan”, eye roll).

In flash, I’m attaching the following ActionScript to the button:

on (release) {
gotoAndPlay(2);
getURL(“getstarted.html”, “content”);
}

It’s supposed to load the targeted content “content” from the external page “getstarted.html” into the iframe without reloading the page on which the Flash button resides. From everything I’ve read, the above ActionScript is correct.

Butt what it’s doing, is loading the correct content, but it’s launching a new tab and loading it there instead of the iframe.

Ideas?

Thanks.
