hitTest mis-script

Hi, I will be very grateful if someone can help me with the following:

I have attached a mc to the mouse and then my buttons no longer worked as the mc was between the pointer and my buttons. So I changed my buttons into mcs and put hitTest script on the mcs. I probably mis-scripted this but the desired effect (ie that the button/mc disappears on rollOver and appears again on rollOut) is not achieved - it disappears but does not reappear on rollOut. This is the script:

attachedToMouse_mc.onEnterFrame=function(){
if (this.hitTest(wasButton_mc)){
hit = true;
trace("hit");
wasButton_visible = "0";
}else if (hit != true) {
trace("no hit");
wasButton_visible = "1";
}
}

I used the trace to determine whether this script was working and "no hit" works initially until rollOver and then no more.

What is my mistake?
Michelle.

These changes may halp.

attachedToMouse_mc.onEnterFrame=function(){
if (this.hitTest(wasButton_mc)){
hit = true;
trace("hit");
wasButton._visible = 0;
}else if (hit != true) {
trace("no hit");
wasButton._visible = 1;
}
}
