I want to give the participant a direct link to jump back to a certain question.
There is a kind of summary of his/her previous answers.
I'm asking if he/she want's to change any of his/her previous answers. If so, the participant should be able to click on something, which will redirect him to whatever should be changed.
I thought about adding a simple radio list question, where he/she can select, which part should be changed. But the condition designer doesn't help, because I can't set any condition for a previous answer depending on a later one.
Limesurvey doesn't really allow jumps within the survey. However, there is the question index feature, which allows jumping in some way. I have never used it, so I don't really know how it exactly works, but you might want to have a look at this.
