I am having some problems in debuggging the following segment of code. So, I
need your help folks.
<code>
<script language="JavaScript">
NewsThemeLinks = [
["newsAndTheme.gif",
["<font size='-1' face='arial'\>Nov 10 News
Item</font\>","NewsDload.asp?ID=87",""],
["<font size='-1' face='arial'\>Dec 20</font\>","NewsDload.asp?ID=102",""],
],
]
</script>
......
.....
after some other code
....
...
....
<div id="newsAndTheme" style="position:absolute; width:598px; height:24px;
z-index:16; left: 178px; top: 138">
<SCRIPT LANGUAGE="JavaScript" SRC="news-theme-01.js"
TYPE="text/javascript"></SCRIPT>
<LAYER ID=xqq VISIBILITY=SHOW
TOP=&{document.layers[document.layers.length-1].top +
document.layers[document.layers.length-1].document.height + 20};>
<!-- My View Start -->
<layer id=myviewstartlayer visibility=show>
<table width=598 border=0 cellspacing=0 cellpadding=0>
<tr>
<td align=left><img src="myView.gif" width="584" height="23"></td>
<td width=6>
<table cellpadding=0 cellspacing=0 border=0>
<tr>
<td width=6 bgcolor="#ffffff"> </td>
</tr>
<tr>
<td width=6 bgcolor="#cccccc"> </td>
</tr>
</table>
</td>
</tr>
</table>
</layer>
<table width=598 border=0 cellspacing=0 cellpadding=0>
<tr>
<td height=27 >
<table cellpadding=0 cellspacing=0 border=0>
<tr>
<td width=299 bgcolor="#ffffff"> </td>

<tr>
<td width=299 bgcolor="#cccccc"> </td>

</table>
</td>
<td>
<table cellpadding=0 cellspacing=0 border=0>
<tr>
<td width=299 bgcolor="#ffffff"> </td>

<tr>
<td width=299 bgcolor="#cccccc"> </td>

</td>

</table>
</LAYER>
</DIV>

And I just have to use Netscape V4.XX browser ONLY as this is an intranet
project.
When I display the page the above segement is in, and see the "source code"
of navigator, I see the following:-
<start of view source>
<div id="newsAndTheme" style="position:absolute; width:598px; height:24px;
z-index:16; left: 178px; top: 138">

TOP=&{document.layers[document.layers.length-1].top +
document.layers[document.layers.length-1].document.height + 20};>
<!-- My View Start -->

The output from the .js file gets pasted in after layer "myviewstartlayer".
and the table within "myviewstartlayer" layer gets repeated. The layers are
getting messed up when displayed in the browser.
Can anybody tell what's the problem???

I know the above code is too much but I thought I should give all the
details.
Thanks for your time and effort.
