Linking within a frameset

So this thread is a little boring, but I have a tree component in my flash video that I would like to link to html pages, opening them in another frame of a frameset. The component is llinking fine, but I can’t get it to open the page in the intended window. I am using the Action Script below to get the designated URL from each link of the tree. The frame I’m trying to open the page in is named “content”. However, this code causes the linked web page to open in a new browser window. Any suggestions?

treeL.change = function() {
var item = theTree.selectedItem;
var earl = item.attributes.url;
if(earl) {
getURL(earl, “content”);
}
}
