I am designing a database driven site using ASP and passing some parameters using QueryStrings. I think I am going to switch to Session variables (which makes more sense anyway) but I am having a problem that may come up again. Everything works just fine in IE, but when I try to view an article in NS I get a page stating "The parameter is incorrect". The process goes like this: You select which list of articles you would like to see, there are 3 different sections. On the list page, the title of the article and a brief description are pulled from the database and displayed. The title is made into a link that uses a QueryString to pass the title as is to the display page. This works great for IE, but not for NS. My theory is this, IE automatically replaces spaces in a querystring with %20 while NS does not, causing a problem when display.asp tries to bring up the selected article. Can anyone confirm or clarify this for me? I am also looking for resources related to the difference between IE and NS as far as using tables for layout formatting.
