Take a look at the use of innerHTML here and see if you're writing to
read-only property:

ml.asp

On the other hand, I think you could simplify your code a lot:
1) I see that you have one DIV containing immediately another DIV.  
Remove
of them if possible.
2) To make your code easier to read, it is not always necessary to 
delimit
attribute values with quotes, providing they satisfy some conditions.  
Look
at 4th paragraph of this:
http://www.w3.org/TR/html4/intro/sgmltut.html#h-3.2.2
3) </tr> and </td> are optional.  Remove them to make your string 
shorter.

Have your tried to print the string in an alert box to debug?

> Hi Solker,

> document.all(a).innerText=3D'' &&  document.all(a).outerText=3D''
