hi there, for awhile i’ve been using the gotoandlearn.com mp3player when wanting to provide music in flash, the other day i decided to rewrite into a class. my textfield returns “undefined”, which is frustrating because i know the nodes are being parsed into the loadXML(); method.
the problem i’m having seems to be in the playSong() method, the [COLOR=DarkGreen]sa[/COLOR] Array hasn’t retained the information that had been parsed into it when the loadXML(); method is initialized.
below is the class i’m working with;
thank you to anyone who can help me out here, i’ve been trying to figure it out for a couple of days now, this is a last resort…
