Shopping Cart Not Working

  #1  
Apr 18th, 2004
Hey All,
i'm having real trouble with this. ok, i have a login page where the user logs in. they put items in the cart and then go to addorder from to place order in database. only problem is i can't get it to work. i think the problem is that its not reading login and getting required userid from customers table, but i can't fix it. i don't know what to do with it. i'll paste in pages. any help would be greatly appreciated.

LOGIN.ASP
