Now time to go back into an array: $colorarray = explode (" ", $colorstring); Next I count how many times particular values show up in an array: $colorvalues = array_count_values ($colorarray); *Note: This gives me an array with how many times each value shows up. So if the user selects three items in column 1 of the matrix, the array will show the key as 1 and the value as 3. Next I count how many questions have been answered: $colorcount = count ($colorarray); With $colorcount and $colorvalue I can then do the following to give the appropriate error message: if ($colorvalues17[1] == '')

     { echo "This is not a problem.";}
     else{
         if ($colorvalues[1] >1)
                 {echo "You have too many colors ranked first (column 1).

Please change your answers so you only have one item in the first column.";}

     }
   if ($colorvalues17[2] == '')       { echo "This is not a problem.";}
     else{
         if ($colorvalues[2] >1)
                 {echo "You have too many colors ranked second (column 2).

Please change your answers so you only have one item in the second column.";}

    }

1. There is also called a function elseif() so you dont have to write if () {

    else
      {
        if () ..code code..;
      }

} just write: if () {

    elseif()
      {
        .. code code ..
      }

} sorry small mistake it has to be:

if () { } else {

    if () { .. code code ..}

} just write: if () { } elseif () {

    .. code code ..
