Help with mail form...

Question

Can someone please tell me why when I submit this form it gets stuck on the "sending" frame instead of advancing to the "acknowledge" frame as it should?  The code is found near the bottom...."if(this.sent == OK)" blah blah blah....  Been trying for hours now and im sure its something simple...

Answer 1

Unless OK is some variable that is defined somewhere that you aren't showing, it is otherwise a String and needs to be quoted...
messageget.onLoad = function() {
            if(this.sent == "OK") {
            gotoAndStop('acknowledge');
            else {
                if(this.sent == failed) {
                    gotoAndStop('failure');
                    failuretxt.text = this.reason;
If that doesn't solve matters, try tracing the value of this.sent ahead of that if test... trace(this.sent);
