Hi Everyone,

Its been a while since I`ve played with flash but I`m trying to make a menu that when someone clicks on a university, the university appears and when they click on it again, it disappears.

movieVar = 0

mcUni.onEnterFrame = function()  
{  
uniMenu(mcCov, movieVar, mcContent.mcUni);  
}

uniMenu = function (cover, movieVar, uni)  
{  
cover.onRelease = function ()  
{  
if (movieVar == 1)  
{  
uni.\_visible = false;  
movieVar–;  
}  
else if(movieVar == 0)  
{  
uni.\_visible = true;  
movieVar++;  
}  
}  
}

The problem is the movieVar never outputs and doesnt appear to update and wont switch on and off when I click the button. it will switch on, but not off.

Any help?
