Object Expected

I have a links in my asp page that points to different crystal reports.  On the page the user can hoover over the link, and view a description of the report. When they go to hoover over the report name I am receiving the error object expected.  
The following is the link I build, and the javascript that I call:


<A target="_blank" ONMOUSEOUT="javascript:dis();return false;" ONMOUSEOVER="javascript:test(<%=n%>,'bob');return false;" Href="/ReportFinder/<%=rs337(0)%>.rpt"><%= MyArray(I)%></a>


<SCRIPT LANGUAGE="JavaScript">

<!-- This script and many more are available free online at -->
<!-- The JavaScript Source!! http://javascript.internet.com -->

<!-- Begin
function test(z,who)
{

add.value= who
add.style.width=500
add.style.top = 350 + z
add.style.left = 400

}
function dis()
{
add.value=""
add.style.height=0
add.style.width=0
}
//  End -->
</script>

<font size=2 face="arial narrow">
<input type=button name="add" style="position:absolute;background-color:yellow;color:black;border-color:black;height:0;width:0">


Any help would be grateful!!
