Thanks for your collaboration and efforts to pin down this problem. I've modified the site to match the registration statement as you wrote (attached in the modified solution). However there are no errors reported by JustCode when the solution is opened. Can you confirm that you are receiving an error on your side with the solution I've attached. If there is one, could you try refreshing the code analysis (choose from JustCode's menu "Refresh Code Analysis") and see if the error is still showing after that.
Thanks again for your responsiveness.
