Buttons stopped working after click

programming flash
1

I am having some problems with my buttons, after i clicked them they seem to stop working.

Ive put my version online http://www.roysterken.nl/test_online.swf

I have this code in root :


stop();

// GEBOUW 2
this.gebouw2_mc.gebouw2_btn.onRollOver = function() {
    _root.gebouw2_mc.gotoAndPlay(2);
    _root.x +=2;
    _root.gebouw2_mc.swapDepths(_root.x);
    trace("rollover");
};

this.gebouw2_mc.gebouw2_btn.onRollOut = function() {
    _root.gebouw2_mc.gotoAndPlay(1);
    trace("rollout");
};

this.gebouw2_mc.gebouw2_btn.onRelease = function() {
    _root.gebouw2_mc.gotoAndPlay(7);
    _root.x +=2;
    _root.gebouw2_mc.swapDepths(_root.x);
    trace("release");
};


// GEBOUW 3
this.gebouw3_mc.gebouw3_btn.onRollOver = function() {
    _root.gebouw3_mc.gotoAndPlay(2);
    _root.x +=2;
    _root.gebouw3_mc.swapDepths(_root.x);
    trace("rollover");
};

this.gebouw3_mc.gebouw3_btn.onRollOut = function() {
    _root.gebouw3_mc.gotoAndPlay(1);
    trace("rollout");
};

this.gebouw3_mc.gebouw3_btn.onRelease = function() {
    _root.gebouw3_mc.gotoAndPlay(7);
    _root.x +=2;
    _root.gebouw3_mc.swapDepths(_root.x);
    trace("release");
};

And this is the code for the “X” button in the tooltip:


this.tooltip_close.onRelease = function(){ 
    trace("close");
    this._parent._parent.gotoAndPlay(1);
};

When i trace “this._parent._parent” it gives me _level0.gebouw3_mc.

While “_root” gives me _level0 same for “this._parent._parent._parent”. But its not working like i want it to, see it here:

What am i doing wrong? ive been working on this for the last past days now and i still dont get it :frowning:

Thanks in advance for your help!
