Parse error: parse error, unexpected T_INCLUDE, expecting T_CASE or T_DEFAULT or '}'

switch ($printjob){

include ('includes/PrintQuotes/standardflyer/1sided_uncoated.php'); 

default:
		$printjob = 'null';
	}

Execute the whole script, and this appears:
Parse error: parse error, unexpected T_INCLUDE, expecting T_CASE or T_DEFAULT or ‘}’

Now, if I put the content in the 1sided_uncoated.php file in the place of the include tag, it all works fine.

I’ve attached the PHP file where the first code is in (standardflyer_settings.php), and also 1sided_uncoated.php.

Any help appreciated
