Gravity Forms merge tags in templates?

The ability to use Gravity Forms’ merge tags in your post content might be helpful to you here:

If you need more specific control, you can fetch an entry like so:

$entry = GFAPI::get_entry( $entry_id );

And echo out a specific field’s value from that entry like so:

echo $entry[1]; // replace "1" with your desired field ID
