On this page, http://bit.ly/pXD3H8, if you just hit submit and not fill anything in you'll see my error messages.

Any thoughts on why the "0" is showing up at the end of this line.

Please use the"BACK" button to try again.0

Code below.

It looks to me like you have a misplaced { }. Instead of

     if ($errorCount>0){
          echo "Please use the\"BACK\" button to try again.";
     }else{
               echo "You Got PAID: $";
     }
     if ($hours>40){
          $OTHours = $hours - 40;
          $OT = $wage * .5;
          $pay = $wage * $hours;
          echo $OT * $OTHours + $pay;
     }else{
     $pay = $wage * $hours;
     echo $pay;
     }

it would make more sense to be like this

     if ($errorCount>0){
          echo "Please use the\"BACK\" button to try again.";
     }else{
               echo "You Got PAID: $";
               if ($hours>40){
                         $OTHours = $hours - 40;
                         $OT = $wage * .5;
                         $pay = $wage * $hours;
                         echo $OT * $OTHours + $pay;
               }else{
                    $pay = $wage * $hours;
                    echo $pay;
               }
     }
