I am stuck on how to update a custom entity with Web Services in CRM 4.0. I am working from the great example of how to call web services with JavaScript here:
http://blog.customereffective.com/blog/2008/03/custom-auto-inc.html
I have the first three parts of the solution working...
1. I read the current setting ID, name and value and parse the returned values into variables.
ENTITY: new_customsetting
SCHEMA: new_customsettingid (ID), new_settingname (Text), new_settingvalue (Text)
2. I validate the new_settingvalue is not in use in my Account table. If it is in use, I increment until it finds a unique value.
3. I stamp the new (assumed unique) value into the current Account record.
4. I'm stuck when trying to write the new counter value back into my new_customsetting entity. I am creating the XML and using previously declared variables but getting a server side error as follows. I've been unable to find any clear documentation
on any changes from CRM 3 to CRM 4. The code snippet is from Will's CRM 3 example with the updated ns values and the SOAP header... but I'm not sure what else has changed.
Any pointers in the right direction are appreciated.

Thanks for the help.
