Security Assist Errors on PowerCMS Pages

There are several pages, such as admin/index.php or manage_users.php, where I see Dreamweaver8 flagging errors when I open the page.

The errors range from the record set having no connection to generating a Javascript error such as "While executing onLoad in WADA Repeat Selection.htm a Javascript error occured."

Why are these obvious errors in the code?

Is it the nature of the PowerCMS product that WA users who already own Security Asssist and many of your other products were not meant to make changes to the PowerCMS pages?

My goal in this is to avoid forcing the user to log in a second time, when they have already logged in elsewhere in the system.

Rather than remove the authentication code in index.php, what variables should I set so that the system processes an Admin or Super Admin user?

Thanks.
