ACTION = Request.ServerVariables("SCRIPT_NAME") equals the name of the page itself so the CGI is the page itself. This means if you decide to rename the page you don't need to alter the ACTION part.
<FORM ACTION="<% = Request.ServerVariables("SCRIPT_NAME") %>" METHOD="POST">

Graphics Capability:

chkArr[x] checks one the Graphics radio btns based on the switch statement above.
<INPUT TYPE="radio" <% = chkArr[1] %> NAME="Graphics" VALUE="lo">Low
<INPUT TYPE="radio" <% = chkArr[2] %> NAME="Graphics" VALUE="md">Medium
<INPUT TYPE="radio" <% = chkArr[3] %> NAME="Graphics" VALUE="hi">High

Your name:
strUsername is passed through the POST back to itself
<INPUT TYPE="text" NAME="UserName" VALUE="<% = strUsername %>" SIZE="20">
<INPUT TYPE="submit" NAME="Submit">
