Looping and adding event listeners

1

Im getting a headache and an error:( worst combination ever!

Im just trying to add an event listener to all of the objects in an array I have posted my error and the code below.

Anyone got any ideas as to by this is happening?

error:
TypeError: Error #1006: addEventListener is not a function.

code:
mainMenuArray = new Array([introButton], [photographyButton], [graphicsButton], [contactsButton], [projectsButton], [linksButton]);

private function firstMenuListeners()
{
for(var i:int = 0; i < mainMenuArray.length; i++)
{
mainMenuArray*.addEventListener(MouseEvent.CLICK, mainMenuClick, false, 0, true);
}
}
