"Find address on map" button does not appear on user profile form

Did not work for me. When I replace the code I get the following errors:

If I replace the
$form['#form_id'] == 'user_profile_form'
with
$form['#form_id'] == 'user-profile-form'
The errors disappear but the button is still missing.
I am running drupal 7.26 with gmap 7.x-2.8 and Location 7.x-3.2-beta2

This issue isn't just for the user profile form.
The button won't show up anywhere else, aside from the node edit form.

Doesn't work with Inline Entity Form module.

I was able to make this work for a user profile2 location field. It required some custom code, but really this should be expanded to work with all profile types and then added to this module. This code is setup to work with a profile2 profile type called "personal_information", change that to your profile type machine name.
