This is the version of the script which is valid for standard official html compliancy:
<!-- opentracker html start -->
<!-- opentracker html end -->
If you replace all code with this code, then your test program will ok the script.
Please note: make sure to check server number, for example server1, & make sure that you send your data to the correct server.
Also be sure to specify your domain/url name instead of www.mysite.com.
We do not use it because it potentially adds load time, which although a thousandth of a second, is still adding time.
