	if ( $two == $comm)echo "selected ";
	echo ">$two</option>\n" ;
}
?>

The error is message is straight forward. The variable $places you past to each() is not array or an object. How is the $places variable defined and why are casting it as global?

hi, thank you for your reply. the $places are a set list of places in the variables file. don't know why I did the globals, think because it was set list.

What does that mean?
