[dev] Variables that I can use in queue customer notifications messages

Hi list. I'm using OTRS as HELPDESK dispatcher in my company, but I've got a problem with QUEUE Notifications. I need to customize a message, based on the ticket created by the customer on its email, and to put the internal note that the agent puts in, into the automatic ticket state change notification, because some agents are closing tickets without filling up an empty answer, just with the close link, and the customer needs a little bit more information about its ticket resolution. There is a list of Variables that can I use with automatic queues notifications to customize it, like to include in that message??? Because I've tried a lot and nothing works. Or do I need to modify something to access those internal notes and answers to pass them in the notification to the customer? Thanks... CESAR AUGUSTO SANCHEZ Network Engineer.
