ok thanks, manual not too clear on this.
follow up question - I have created a token and tried to send the email invitation to myself and got this:
There were no eligible emails to send. This will be because none satisfied the criteria of:
having a valid email address
not having been sent an invitation already
not having already completed the survey
having a token
Email is definitely valid, not sure where the problem is, again, manual not too clear
Thx
