Thanks for the reply. 

I did add those keys and sections to the web.config file before I posted my first questions about getting this work.  I have since double and triple checked the entries and look exactly like how you outlined them here as well as in the documentation.  However my problem still persists with  the 'Type initialization error'.  Any other ideas I can try?

Also here is another questions for you it is one I will have to deal with in the near future.  How is the best way to handle 2 stores on one DNN instance each on different portals, but they both use LinkPoint and both will need to use the DotNetChargeProvider?  By modifing the provider and adding the Referrer property into it with the URL of one of the stores how can I handle the other?  Thought I would ask your opinion.  I did purchase the CATALook source so if I need to change something in that I can.

Thanks again!

Thanks for the info.  I switched back to the original DotNetChargeProvider .dll file, added the parameters you listed into the additional parameters area and I tested it again. 

I still got the same error.  I did grab more info about it from the Log Viewer though and was looking into the source code to see where it might be occuring at.  Here is the error in full:

From what I can tell by the error and the source code is that the error is occuring when it tries to kick in the DotNetChargeProvider, but given that I have the entries for it in the web.config file I am still not sure why this error is occuring.  I will double check the values and places where I have the changes to the web.config file.

Thanks!
