/*1. To show the ads vertically, change the script on the page to


<script type="text/javascript">
randomorder(adblock, '<br><br>')
</script>

2. To show the ads horizontally change the script on the page to


<script type="text/javascript">
randomorder(adblock, ' ')
</script>

3. The following portion of the code determines how many ads to display


var randomorder=new Array()
var the_one
var z=9
for (i=0;i<targetarray.length;i++)
randomorder[i]="i"

The value of the "z" variable is very important. If you have 20 ads but only want to display 4 ads at a time, you would change the value of the "z" variable to "z=16" (without the quotes). This means that out of 20 ads, 16 will be hidden.*/
