[Resolved] [Resolved] If with multiple OR include

[coders4hire]

I don't understand why this isn't working. If someone could lead me in the right direction, I'd appreciate it!

if(strlen($surveyid)!=6) or (substr($surveyid,0,1)!='S') or (substr($surveyid,0,1)!='I') or (strlen($firstname) < 1) or (strlen($lastname) < 1)
	require('regerror.inc');
	}
	else
	{
	include('next.inc');
	}

Hmm. Perhaps you're used to a different coding construct, but in PHP, the entire IF statement needs to be enclosed inside parenthesis (sp?), like so:

if(strlen($surveyid) !=6 || substr($surveyid,0,1) != 'S' || substr($surveyid,0,1) != 'I' || strlen($firstname) < 1 || strlen($lastname) < 1) { 
    require('regerror.inc'); 
    } 
    else 
    { 
    include('next.inc'); 
    }

NOTE: I also converted the 'or' keyword to the logical operator '||', simply because I always use those operators (||, &&, etc.). I believe they are both compatible, not 100% sure though. At any rate, feel free to use what you prefer. More about those operators here if anyone's interested.
