Only working for admin users?

Hi, I’m using this plugin to allow logged in visitors to edit some of their own content. It is working for my administrator user, but when I try it with a subscriber user, it doesn’t retrieve any data. This is the code I’m using:
`gform_update_post::setup_form( $edit_post_id );
gravity_form(5, $display_title=false, $display_description=false, $display_inactive=false, $field_values=null, $ajax=true, false);`

Do I need to add something to allow non-admins to do this?
