Why isn't my coupon code working wtih my tickets?

Are you having troubles with a coupon code not validating properly? Does it work for some tickets and not the others? If you find that all of your settings within the coupon are correct, then it can be that there is an issue with the reference names in the ticket box fields.  

To fix this, go back to the layout tab; once there, go ahead and edit all the ticket boxes, and make sure each on in the "Ref Name" has a numerical number as well as a letter. This can be done through the advanced options editing in the ticket box. This will allow coupon codes to be linked correctly to each ticket box that it needs to be used with.
