I am using the builder, but am trying to add in a line of custom code so that after the instruction screen, the program picks one of the 8 excel sheets in my folder. Each sheet is a different stimulus set order and each participant only needs to complete one of the excel sheet/stimulus sets. Since I am not used to writing code and instead rely on the builder, I am in need of help figuring out how to have my code randomly picking one of the excel sheets to read from.
Any advice is welcome. Thank you.
