Web Service Not Working [modified]

Good people, Hello. Our webservice is not working. We should be receiving information via an HTTP POST. However, nothing is working. Below are the code files. Let me know what you think. Thanks in advance for any help or information you can provide. (By the way, some information (e.g. class names, connection strings, etc...) has been removed or changed in order to hide any sensitive information.

Can you please post just the webservice implementation instead of all? Right now, i don't see any webservice present... is there any? You need to have WebMethods in order to call webservice methods. Kindly re-check and update the question with it.

Thank you so much for replying. I have cleaned up the code to only include the web service code-behind and related ASP/XML code. Thanks in advance for any insight you can provide.
