[otrs] Editing the auto-reply parameters

Hi, I'm trying to make the auto-response system to send this text in the SUBJECT field of the letter:

...

[Company_Name#Ticket_Number] Re: _The_subject_of_the_original_customer_email_

And to do this I use this code in the SUBJECT field of the auto-reply:

...

[Company_Name#] Re:

But instead of the result I need to get I have this as the email subject:

...

[Company_Name#1000602]

Any ideas on what I am doing wrong?
