Script to pass Aweber data to a hidden field

I've seen this done before but can't remember where.

I'm trying to move people from one of my Aweber autoresponder lists to the other very easily.

My goal is to send them an email with a variable in the link that pre-populates email input field on the landing page I take them to with their email address.

however, I want that email address form "hidden" from view and for them only to see the "Submit" button.

That way I can send them to the page and say if you want to be on this list or whatever...just click "Yes"

Anyone know how to do that?

 

<input type="hidden" 

Code (markup):

Is that what you mean ?
