We organise a conference and use e Breezing form to order tickets.
We have special tickets for the presenters quests and the sponsors quest and organisers. They get a promotional code via email (e.g PGUEST002 or SGUEST005 or ORGANISER003) and they have to enter it to a text field (element name: SPECJEGY.
We have validate this field. I would like to create a script which only allows to submit the form when the entered valeu of SPECJEGY text field starts with "PGUEST" or "SGUEST" or "ORGANISER". any other case gives back a message "Invalid promotional code".
