There are 4 pages total.
Index.asp which contains the frameset
(instructions on how to display the other three pages).
Left.asp which contains the javascript and drop down redirect menu.
Main.asp which contains this content.
Top.asp which contains the banner stuff.
I've made the frames with borders; adjustable; and scrollable; just
for ease of looking at this example.

Frameset code for index.asp:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <title>Drop down Selects and Frames</title> </head> <frameset rows="150,*" cols="*" frameborder="Yes" border="1" framespacing="0"> <frame src="top.asp" name="topFrame" scrolling="Yes"> <frameset cols="320,*" frameborder="Yes" border="1" framespacing="0"> <frame src="left.asp" name="leftFrame" scrolling="yes"> <frame src="main.asp" name="mainFrame"> </frameset> </frameset> <noframes><body> </body></noframes> </html>
