I created a survey.
Create a Survey campaign.
When i get to the templates tab to insert the Email variables
choose survey and URL then insert
It shows $surveys_survey_url_display on the template
finish the survey campaign
Then send the survey campaign to a contact to see the outcome.
I see the same $surveys_survey_url_display in the contacts mail.
the variable doesn't change to the value.
the link is not provided for the receiver of the emails
