Well, ok, but now I'm confused. You were talking about passing a DataSet in your original post. Now you say that you're not passing the DataSet, you're passing XML. The error message you posted contains this:

SRA.ParkerWS.Service1.PostData(DataSet dsM, String lcCompany, String lcName, 
String lcTitle, String lcEmail, String lcAddress, String lcCity, String lcState, String lcCountry, 
String lcPhone, String lcType)

Which certainly looks like a DataSet to me ... but, I don't know if this particular method (PostData) is being called from the client or if it's something that's private to the WebService itself.
