Sorry for top-posting, gotta configure my mail client better later. Small error here: }while( ($three == $one) && ($three == $two) ); Change to: }while( ($three == $one) || ($three == $two) );

Before you add a number to a string make sure that the number is not in any of the other ones if they exist. Use a do-while loop on it... $one = rand( 1,20 ); do { $two = rand( 1, 20 ); }while( $two == $one ); do { $three = rand( 1, 20 ); }while( ($three == $one) && ($three == $two) ); echo "One: $one\n"; echo "Two: $two\n"; echo "Three: $three\n"; HTH -- Ray On Mon, 2003-10-27 at 05:26, Ian Gray wrote: > I am tring to output 3 different random numbers between 1 > and 20 into 3 different strings.
