I'm using the revised Price Ladder question from the Question Library. First, you have done a FANTASTIC job incorporating all the things we've talked about before and it looks great. I think my clients will be very happy with the overall look and feel. I added a little code to show a message once the final price was reached and the exercise ended, but otherwise it looked great.
I've been testing and looking over how the data is stored. I have 5 price points and I did add the additional variables to account for that as it instructed. I've had some odd behavior in my data though. What exactly is the the Fixed Response variable supposed to represent? The Dynamic response seems to be correctly showing me what answer I chose, but in some cases the Fixed Response is different. I also had one case where the I only answered 3 prices but there was a random value in the Fixed response for the 5th price. I even had one case where everything was blank in the data.
I have removed the previous button just in case there was some bad behavior because of that (although I don't recall using it).
I'm going to be doing a bit more testing to see if I encounter other issues, but for now, I'm hoping you can explain the Fixed Response values for me.
