AS3, scroller #1137 error

Question

Hello,
This is an AS3 scroller I've been trying to convert from AS2.

I appreciate the help, but I'm still getting '#error 1137 incorrect number of arguments'. How do I get this scroller to work?
Thanks,

            mouseX = Math.ceil(mouseX);
        }else{
            mouseX = 20;
        }

        if (mouseX < mouseMin && menuX < 1060) {
            diff = (mouseMin-mouseX)/20;
            BUTTON[i], x, (menuX+diff);
        }else if (mouseX <= mouseMin && menuX >= 1060) { 
            diff = Math.ceil((mouseMin-mouseX)/15);
            diff = diff + (menuX - 1060);
            BUTTON[i], x, (-500 + diff);
        }

            diff = (mouseX-mouseMax)/20;
            BUTTON[i], x, menuX-diff; 
        } else if (mouseX >= mouseMax && menuX <= -500) {
            var diff:int = 0;
            diff = Math.ceil((mouseMin-mouseX)/15);
            diff = diff + (menuX + 500);
            BUTTON[i], x, (1060 + diff);
        }
    }
}

Answer 1

Math.ceil only takes one argument. You are passing two into it @:

menuX = Math.ceil(BUTTON[i], x);

Answer 2

As I stated in the answer to your previous question, setting the property x of BUTTON[i] is done like this:

BUTTON[i].x = -500 + diff

NOT like this:

BUTTON[i], x, (-500 + diff);

EDIT
Also note, your lines checking for i < 12 will always evaluate to true since i is a counter from 0 to 5.

EDIT 2
Also note, your code initializing your array should be outside of the EnterFrame event handler as you are needlessly reinitializing the array on each frame.
