New Post: Checking for the value of a token

Thanks Rob. Could I trouble you for an example code snippet to test for the existence of a value in a token and then display that value along with some arbitrary text? I am having trouble working out the syntax... I have had a poke around in the BackOffice->Admin->Help and it is quite descriptive but I am having trouble getting started with the correct approach.

All I am trying to accomplish is to add the Promotion Code into the relevant templates. But only insert it if a Promotion Code has been used. I only really need it inserted into the email template.

Regards
Aaron
