So i'm trying to take an existing HTML/CSS website and add a contact form right? I figure it would be easy but i'm having a few problems with the web config file. I keep getting a "customer errors" error when I try to view it on my server. I tried adding both code tidbits to my web config file but no luck. Any suggestions of what I can do to get around this and what I can do to avoid this problem in the future?
