Oops; the problem is that that code is self-restricting.

Any value in the cookie overrides the value from the form; so, once you submit once, you can't submit again.

Corrected part: (ASP only)

<%@ LANGUAGE="JAVASCRIPT" %>
<% var style = new String(Request.Form('style'));
if(style==null || style==''){
  style = new String(Request.Cookies('style'));
  if(style==null || style==''){
   style="default";
  }
}else{
   Response.Cookies('style') = style;
}
%>

Seems like a minor thing, but it'll make all the difference =P

yay it works!! the only thing is the cookie isnt working. i have added a second page to the folder and the 2 pages link to eachother so as to test the asp cookie however its not working. Also, how do you make the default style sheet be styles_1.css? Thanks,

hmmm, i had a quick visit to your page (from that link) with cookies cleared and cookie notifications switched on. The first event is a request to set the style cookie to 'undefined':

This page wishes to set the cookie
   style="undefined"
 
This value will only be sent to documents on the server grafax.co.uk, and paths that are starting in /.
 
The cookie will be deleted when Opera is closed.
----------------------
Full cookie request:
 
style=undefined; path=/

So, that means the if(style==null || style='undefined') checks were probably correct... it's a bit weird that O_o. Go with a full test just in case:

<%@ LANGUAGE="JAVASCRIPT" %>
<% var style = new String(Request.Form('style'));
if(style==null || style=='undefined' || style==''){
  style = new String(Request.Cookies('style'));
  if(style==null || style=='undefined' || style==''){
   style="1";
  }
}else{
   Response.Cookies('style') = style;
}
%>

the line in blue is where you should define the default stylesheet's filename suffix, so a '1' will make the default sheet /styles/style_1.css.

Yay it works!

2 more things.. how do you make it so when you select a new style sheet for the pages it goes there automatically when you press it, rather than having to press the submit button?

Also, how can i make it so the selected option is the style sheet being used? for example, if style sheet 2 was being used, option 2 in the menu would be selected?

Thanks,

Max
