$_POST[$value] not working

It won't let me grab the value I'm trying to grab $_POST['email'] in this instance but I'm using a dynamic form that passes the key that was edited through $_POST['key'] which I do $key = $_POST['key'] (so now if email was edited $key = 'email' and then the value comes through $_POST['whatever value it was'] which I try to catch like this $value = $_POST[$key] but it says that index 'email' does not exist. but I can do this $value = $_POST['email'] and I can echo $key. so both of those are valid but the whole $_POST[$key] doesn't work.

 

any help is apprecieated thanks.
