A few things. The way they have it coded now (if functioning), it would immediately change screens after the first dropdown is selected. It isn’t quite working now because it should use the “getText” block rather than the “getChecked” block in the comparisons. You could use this to choose something from the first dropdown which could them take them to a screen with the 2nd dropdown, etc.
If they go that route, my suggestion would be to have them get a sheet of paper and map out the final results. What are the final screens going to be? Then have them draw a path of how you would get there. If there are three drop downs and each drop down offers 3 choices, that is in theory up to 27 different final landing screens (3 x 3 x 3) … if you want a different landing screen for each possible combination which could be a lot of coding.
Another option would be similar to the link below where each choice awards “points” towards a final screen. In this option, I would still have them map it out, but you can see how making one choice may score points for multiple final choices and in the end, the highest score determines the final result.
There are probably other ways to do it and there may be a way to code it so the finish button does the calculations, but just my 2 cents.
