Not an expression but a
placeholder
to insert dynamically the survey ID ( {SID} )
So you can use html code like:
Code:
<a class='printlink' href='index.php/printanswers/view/surveyid/{SID}' target='_blank'>Print your answers.</a>
Remember:
1) Works only for the final completed page (not during the survey)
2) turn on the survey option "Participants may print their answers" (btw this setting controls the default print link display)
