Hey guys i am having a problem coding here. I want a txt file to be created to me when an user submits his name on the html form. But it gives an error in line 5 of this code:

<?php

  $name = $_GET['firstname'] 

 $fh = fopen('name.txt', 'a');
 fwrite($fh, 'Name: '."".$name ."\n");
 fclose($fh);
 ?>

it gives this error:

Parse error: syntax error, unexpected T_VARIABLE in 
         /home/a1781682/public_html/action_page.php on line 5

Any help would be appreciated!
