web designer errors

Hello,

I've created a web project in web designer.

I have 2 questions:

1- the project  has a session module and a start module.

In the start module i have a switch with a condition on a boolean variable X

I dont know how to do a condition like this : Not(X), when i set it like this, i have an error.

2- I set up and deploy the web project with Windows authentication, but when i debug i have this error:

HTTP Error 401.2 - Unauthorized You are not authorized to view this page due to invalid authentication headers

Thank you for your help
