Cookie question

Hello everyone-- I'm making a huge form that people access and fill out. The thing is that I am having to check every field to make sure they are entering the correct information spanning 4 pages. So I thought I would use cookies instead of having to pass a ton of hiddens throughout the program. However, I am running into some problems with some cookies not being set etc. The only thing that I can think of is that there might be some kind of limit for the amount of cookies that a page can handle, but I'm not sure if that's the case. Anyway, my question: is there a limit for the number of cookies that a page and process? or is the number of cookies that are used determined by the settings in IE or Netscape? If at all possible I want to try and stay away from having to pass all the variables through the hidden types. Thanks, Jay Paulson
