RE: Again ----
Instead of this: print "Your SID is $PHPSESSID <br>"; ->>>>>> Error here try this: print "Your SID is".$PHPSESSID."<br>"; ->>>>>> Error here Instead of this: print "The persistent background color is: $bgcolor."; ->>>>>> Error here Try this: print "The persistent background color is:".$bgcolor."."; ->>>>>> Error here And why are you using substraction to name a file?. you should not be using dashes in file names.

RE: Again ----
Don't worry about taking variables out of the quotes. In PHP as is today
echo "You are in a $mood mood"; is the same as echo "You are in a " . $mood . " mood."; They should be the same. Also, using dashes in filenames is really not an issue either. 1-2.php is a completely valid filename in Windows and UNIX, so that's not an issue. The key here, as said above, is calling the session vars with $_SESSION['varname'] In fact, you should get used to using $_GET['varname'], $_POST['varname'], $_COOKIE['varname']and $_SESSION['varname'] for all form, cookie, and session data.

RE: Again ----
If you plan on using an array variable inside quotes, make sure you place curly brackets around it:
