**What are you trying to achieve?:
I have two different loops( A and B ), and these two loops based on two different conditions: “high” and “low”. I want to choose one of these loop at the beginning of the task. e.g. a popup window show which condition you want to use: “high” or “low”. if you choose condition “high”, the loop A will work. if you choose condition “low”, the loop B will show up.
I am wondering is there any method to show a popup window, and then send the response variable “BlockCode” to the rest of experiment?
Thank you so much!
