This will let you change the label on a navigation button during a survey.
Select survey settings, layout and inside the next button label put – ^f(‘nextBtn’).valueLabel()^
Within the survey you will need a hidden single question called – nextBtn
This will need to have the required labels for the button
Then script node to change the button labels
Inside this node – f(‘nextBtn’).set(‘continue’);
This will change the button label to “Continue”.
A very handy bit of code for a button that needs to have it label changed during a survey.
