Hi there,
i have assigned your pre defined custom field "field_speaker" to an event.
The value of "field_speaker" is displayed correctly in the front end but not on the invoice.
On the invoice is the string "[FIELD_SPEAKER]" printed.
Any idea what I did wrong? I'm using EB 1.6.9
That tag feature is not supported in version 1.6.9. If you want to use that tag, you will need to upgrade to latest version of Events Booking (version 2.0.4 for now, version 2.0.5 should be released later today)
