==================
I need to set up a 3-question survey for Major Choice in university, Alll question is singal choice question.
Question 1, What is your major? Answer will be 1~9
Question 2, Will you change your major? Answer is Yes or No.
Question 3 Is the future major you will choice. But it will be partially setup base on the previously answer from Q1 and Q2.

For example, if Q1 = 7 and Q2 = No, then the Q3 will automatically set to 4.

Can I make it by LS? Thanks for help!!!

What's the exact workflow?
Q3 is set to 4, but then displayed that the respondent is able to change?
Or is Q3 hidden and set to 4 in the background?

Anyway: use ExpressionScript like
{Q3=if(Q1==7 and Q2=="N",4,Q3)}
with Q2 as Y/N question..
