Price Rules Messages on ticket text

Hi,

I am wanting to use the Price Rule Message data element on one of our ticket designs. I have set up a rule with the Message Type as (ticket text) and put a Price Rule Message data element onto the ticket template in Ticket Design but nothing is printing on the ticket. Does anybody use Message on their ticket text and can anyone advise on what I night be missing. 

Many thanks
