PHP: shuffle() errors

[Christopher]

Code:

function random($num=5,$sep="<br><br>",$type="aff")
{
  if($type == "aff")
    shuffle($aff);
  else
    shuffle($affi);
	
  for($i=0; $i<$num; $i++)
  {
    print $type[$i];
	print $sep;
  }
}

It says "Warning: shuffle() expects parameter 1 to be array, null given in..." Parameter 1 is an array!
