The assignment was to create an animated menu for a fictional search engine. I eventually got one to work and here it is:

Here’s the code:

```auto
var position
var intHide

        function show()
        {
        position = document.getElementById("shopmenu").style
        if (parseInt(position.top) != 30)
            {
            position = document.getElementById("shopmenu").style
            position.top = parseInt(position.top) - 10 + "px"
            }
        }
        
        function showmenu()
        
        {
        clearInterval(intHide)
        intShow = setInterval("show()",10)
        }
        
        function hide()
        {
        position = document.getElementById("shopmenu").style
        if (parseInt(position.top) < 200)
            {
            position = document.getElementById("shopmenu").style
            position.top = parseInt(position.top) + 10 + "px"
            }
        }
        
        function hidemenu()
        {
        clearInterval(intShow)
        intHide = setInterval("hide()",10)
        }

```

“Shop” is the only link with an event.

Now to get the rest of the links to use the same functions. I just simply wanted to pass the value (in this case, which DIV to slide up or down) inside the mouse events “showmenu()” and “hidemenu()” I tried it and am getting a “has no properties” error. Here it is:

Any ideas?
