Currently the {SURVEYURL} parameter is not allowed to be used in the CONFIRMATION email. (although it is available as a option to insert in the Confirmation email)

For this specific client, we need the applicant to be able to go back to their Questionnaire to update details later.
As a reminder of their link, we want to send them the SURVEYURL in the CONFIRMATION email.
As example, the email will say something like:
Thank you for completing the XYZ questionnaire. To update your information at a later stage, please click on {SURVEYURL}

This together with the setting "Allow editing responses after completion" = Yes and "Send confirmation emails?" = Yes, allows for above functionality to become usefull.

We will be fixing this issue. This tickets is to keep track of the fix.
