php - I am trying to pass variables between pages and i am failing -

-

i have been trying pass variable between pages tally score on quiz, reason variables aren't passing between pages want them to, want score 1 if first button hit, , 2 if second hit, of ever 1 hit result 0.

1st page - minus whole load of styling:

<?php  $score=0;  if ( isset( $_post['submit1'] ) ) {      $score=$score+1; }  if ( isset( $_post['submit2'] ) ) {      $score=$score+2; }  ?>  <body>  <center><img src="http://fc06.deviantart.net/fs70/f/2011/002/d/3/purple_blob_pet_by_bunni0222-d36aw4q.png" alt="" align="middle"/></center>  <form name ="form1" method ="post" action ="test1.php">  <input type = "hidden" name = "h1" value = <?php echo $score; ?> > <center><input type = "submit" class=mybutton name = "submit1" value = "1"></center> <center><input type = "submit" class=mybutton name = "submit2" value = "2"></center>  </form>   </body>

this complete second page:

<html>   <head>      <title>test</title>    </head>   <body>     <p>       <?php         $score = 0;         //error_reporting(0);         $score = $_post['h1'];         echo $score;         ?>     </p>   </body> </html>

i appreciate help, if stupid apologise learning how write html , php.

i think problem in line:

<input type = "hidden" name = "h1" value = <?php echo $score; ?> >

to 

<input type = "hidden" name = "h1" value = "<?php echo $score; ?>" >
