Dynamic text and height

hello all,

im trying to find the height of a movie clip containing a dynamic text box loading an external text file. i need to determine the height of the movie clip outside of this function but whenever i try to do that i get the initial size of the movie clip and not the resized size after the external text has loaded. i have tried returning the height to this function but when i trace this value i simply get [type Function].

 [LEFT]
function loadInfoText() {
        info.projectInfo._width =200;
        info.projectInfo.multiline = true;
        info.projectInfo.wordWrap = true;
        info.projectInfo.autoSize = true;
        info.projectInfo.text = this.textfield;
        //info formatting
        info.projectInfo.antiAliasType = "advanced";
        info.projectInfo.thickness = 5;
        info.projectInfo.embedFonts = true;
        info.projectInfo.setTextFormat(info_format)
        
}

any ideas?

thanks,
joe
