Unnecessary Subroutine

print_cell is called from only one place
That is not a red flag
Such subroutines are often valuable for dividing programs into chunks
However, print_cell doesn't actually do anything

  295     sub print_cell {
  296        my $squares = $_[0];  ##import semi-existant array of squares
  297        my $page = $_[1];     ##import html stuffs
  298        my $x = $_[2];        ##import the number that the foreach is on 
  299        my $row = $_[3];      ##import the row we are on
  300        my $cell = "[$row][$x]";  ##get square coordinates for use in naming checkbx
  301                                                                          #    
  302        print ("<td>");
  303        print ("<input type='checkbox' name='choice' value='$cell'>\n"); 
  304        print ("</td>");
  305     }

Most of this is structural
Only the three prints are actually interesting
