How do I select fonts with two (or more) words? never mind worked it out

$mw->Label( -font => "Verdana 18 bold" ); #this works

$mw->Label( -font => "Times Roman 18 bold" ); #this Doesn't Work
$mw->Label( -font => "'Times Roman' 18 bold" ); #this Doesn't Work
$mw->Label( -font => "Times\ Roman 18 bold" ); #this Doesn't Work


$mw->Label( -font => "Times\sRoman 18 bold" ); #this Works
