How do I take a specific post variable from one page to another?

I have two html forms on one page and I want to take variables from only one of the submited forms to another page but not the other variables. How do I do this?

 

Assign a name to the fields...

<input type="text" name="danx10">

Then call it on the other page like:

<?php
echo $_REQUEST['danx10'];
?>

PHP:

 

Okay. But is there anyway I can choose the specific input box depending on which form was submited?
