Alice, I'm not sure I follow you. Are you speaking of the local script or the remote script as far as automation? The local script is executed when a user requests it. The remote script will be executed when your local script uses cURL to "visit" it. No users pressing buttons involved to my knowledge. Unless... is it a form? I'm a bit lost now. I'm not "Midwestern tourist in Malaysia" lost, but I'm definitely a bit confused.
