Two word array Value

I am trying to use array's to populate a group of check boxes for a form. I am getting the checkboxes to print OK, but when the form is posted I am only getting part of the array. Form Page: $vars = array("Main Classroom" => "Main Classroom", "Break Out Classroom" => "Break Out Classroom", "Gym" => "Gym", "Firearms Range" => "Firearms Range", "EVOC Track" => "EVOC Track"); $cols = 4; echo "<form method=post action=twocoltests.php><table><tr><td colspan=".$cols." align=center>Equipment Needed</td><tr>"; foreach($vars as $key => $value){ if (($cols % 4) == 0 ){ echo "</tr><tr>"; } echo "<td><input name=".$key." type=checkbox value=".$value."></td><td>".$value."</td>"; $cols++; } echo "</tr></table>"; echo "<br />"; When I submit the form I am only getting the following having checked the boxes for Mail Classroom and Break Out Classroom. If I eliminate the spaces between the words, I get everything, but when I put the spaces between the words in the array, it cuts off the second word. Not sure what is happening? Array ( [Main] => Main [Break] => Break [Submit] => Submit )
