Button Conditional?

Hey guys/gals I was wondering if you could please help me with an AS3 problem? I have a button that currently when pressed will show an instance object on screen, however what I would like for it to do WHEN PRESSED AGAIN is to remove it just like every other application. AM I right in thinking that would be a conditional, an “if” statement (I’m not sure I haven’t done AS1 in 5 years let alone A3). Any help is appreciated - thank you in advance. :slight_smile:

My Current Code:

Help_Btn.addEventListener(MouseEvent.CLICK, HelpDisplay);

function HelpDisplay(event:MouseEvent):void
{
var Help_MyInstance:LibrarySymbol = new LibrarySymbol();
addChild(Help_MyInstance);

Help_MyInstance.x = 92.70;
Help_MyInstance.y = 46.70;
Help_MyInstance.border = false;
Help_MyInstance.width = 372.20;
Help_MyInstance.height = 220.75;

}
