Hello Joe,

I am using an HTML module created a currency converter it has a textbox and dropdownlist and on the Submit button a page will pop out (using javascript). This page will do the necessary conversion. My code uses a Web Client Class and a third party Html Agility PAck that parse an Html Page.

My problem is it displays an error

Server Error in '/' Application.

Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: That assembly does not allow partially trusted callers.

Any help is greatly appreciated.

Thanks.
