Creating a random.

Hello.

Maybe somebody can help we with this or give me a link to a tutorial.
I am using div tags to sort the my ad-codes at the end of my html files.

<div id='ads_code_1' style='display:none;'>
<!-- Ad Code 1 -->
</div>
   <script language="JavaScript">
    div1 = document.getElementById('adspace1');
    div2 = document.getElementById('ads_code_1');
    div1.innerHTML = div2.innerHTML;
    div2.innerHTML = "";
   </script>

<div id='ads_code_2' style='display:none;'>
<!-- Ad Code 2 -->
</div>
   <script language="JavaScript">
    div1 = document.getElementById('adspace2');
    div2 = document.getElementById('ads_code_2');
    div1.innerHTML = div2.innerHTML;
    div2.innerHTML = "";
   </script>

Code (markup):

Now I want to create a 3rd adcode and alternate 2 & 3 randomly
<!-- Ad Code 2 --> and <!-- Ad Code 3 -->
So that only one of the two shows up.
Does anybody have an idea how to do that.

Thanx and best regards
M.V.
