May I just ask if you are interested in getting this script to work for you? I notice that you have said in an earlier post that you have not uploaded any WebAssist software to your site. The solution pages would need to be uploaded as described in the support files in order to function.
If you are interested in getting the solution to work on your site, it might be helpful if you explain what happens when you upload and test the pages, and if possible provide a link so that people can see what the problem might be.
This solution will work fine for you if you want it to. It does actually do what it says it will.
