What ID are you trying to extract. you might be able to get the ID from elsewhere… rather than having to do this.

Also i cannot see your variable  “StaySure”

Thanks for replying

I am trying to extract from the subject line a request ID from another ticketing system that is emailing in so I can use it else where.

The variable “Staysure” is a field in the properties in the ticket which I am trying to populate to use in canned response or part of a reply back.

This is a sample of the subject line that we recieve. The request id starts and ends with ##xxxxx##.

“Your request has been logged with request id ##28638## Fwd:”

I perform a similar call for termination emails…

substring('{{ticket.subject | sanitize_html}}', (indexOf('{{ticket.subject | sanitize_html}}','Termination: ', 0)+13), indexOf('{{ticket.subject | sanitize_html}}',';',0))

the actual subject line is “Automated Notification: Termination: Person Name ; more text follows…

the first indexof locates the starting point of the word “Termination:” and counts off 13 characters to reach the space after the colon

the second indexof finds the end of the string I want, which happens to be a semicolon

What I would suggest is you replace the Length statement with a second indexof, like “indexof(‘{{ticket.subject | sanitize_html}}’,’ Fwd’,0)
