I have a simple WCF Service created in VS2008 VB. I can attach to it in a web application and a desktop application on the development machine and runwithout a problem. When I tried to copy it to my domain on discountasp.net and try to run I get the following error. I have tried to google information on this without success... Server Error in '/' Application.

This service is a simple service I wrote as a test that will take two numbers add them together and return the result. The code to make the call to the service is: Dim oService as ServiceReference1.Service1Client = New ServiceReference1.Service1Client txtAnswer.Text = oService.GetDataAdd(txtNumber1.text, txtNumber2.Text) The site can be tested with the following URL: http://www.racquetballladder.com/mathcalc.aspx The message says to see the Server Diagonostic Trace Logs for more information. I put in a ticket asking about this log and how to get to it without any help on the reply from support... Can someone give me direction on the next step to solving this problem... I would guess it is just somethingin the webconfig file that needs to be changed but I am new to WCF programming and not to familiar with the setup process... TIA Randyb
