Hi All

Is it possible to compute a value based on previous questions,and add that value into a new question
say a numeric response type of question, and after that reference that value to
auto answer a Single-Choice type of question.

I think it should be possible in the latest version of LS, which is now in release candidate state, using Expression Manager

Hello,

if I'm corret you cannot use the ExpressionManager to select the default answer for a Single-Choice type of question (you can only select one of the available answers from a dropdown list). But it might be an idea to use some Javascript to set the answer of a following Single-Choice question.

Mit freundlichen Grüßen/Best regards,

PLease create a sample survey and attach it here. Explain in detail what kind of calculation you want to do and if both questions will be on the same page.
