TypeError: Error #1009: Cannot access a property or method of a null object reference

hi i am having a problem with just one thing with a button i keep getting this "TypeError: Error #1009: Cannot access a property or method of a null object reference.
at index_fla::MainTimeline/goJobs()"

now here is the the actionscript i am using:

info.addEventListener(MouseEvent.MOUSE_DOWN, goInfo, false, 0, true);
job.addEventListener(MouseEvent.MOUSE_DOWN, goJobs, false, 0, true);


function goInfo(evt:MouseEvent):void{
con.gotoAndStop("info");
};

function goJobs(evt:MouseEvent):void{
con.gotoAndStop("jobs");
};

now in the debugging it shows that this "con.gotoAndStop("jobs");" is the problem

Can anyone help

Does con exist on the timeline where this code resides?

function goJobs(evt:MouseEvent):void{
    con.gotoAndStop("jobs");
};

con does reside on the timeline and when i even remove the con it still gives me the same message

You have your actionscript on a keyframe, correct? Does con exist on that same frame number, or does it appear later on the timeline? If it appears later, you need to move the code

function goJobs(evt:MouseEvent):void{
    con.gotoAndStop("jobs");
};

to the same frame where con is.
