Try using a different name for the variable. I know that Wordpress uses "name" as a public query var, and perhaps that's why it's not working. So rather than using name="name", try this:

Form:

<input type="text" name="unique_name" />

Post Page:

$name=$_POST['unique_name'];
echo $name;

See this list for all query vars: http://codex.wordpress.org/WordPress_Query_Vars#Query_variables
