Re: Undefined index:

There is obviously something else wrong. That's the purpose of isset(); Comment out your line and see what happens. I'd guess the real problem is later in your code when you are trying to do something with $HTTP_COOKIE_VARS["LoggedIn"] even though your isset() test said it didn't exist. WeberSites LTD wrote:

I'm using this code to check if a cookie has a value :

    If(!IsSet($HTTP_COOKIE_VARS["LoggedIn"])) ....
  In case that this cookie is not set, how can i avoid the Undefined index: line in the error log?
