Hello,

I know similar questions have asked been asked before, but I have gotten myself quite confused with potential solutions. So I’m hoping to describe my problem and hopefully be pointed towards a clean solution I can try to implement.

I am looking to present two different tasks (Task 1 & Task 2) twice, under two different conditions (Cond 1 & Cond 2). Each Task has 4 possible trials (Task 1: ABCD; Task 2: EFGH). I want to show 2 of the 4 trials for each task under Condition 1, and then the remaining 2 trials for each Task under Condition 2.

For example, a participant might see combinations such as:

- Condition 1:

** Task 1: AC

** Task 2: EG - Condition 2:

**Task 1: BD

**Task 2: FH

Condition blocks 1 & 2 need to be randomized, but Tasks should remain in order (1 before 2).

Any idea of how to elegantly do this? I am using the Builder for online use. I can use code components if needed, but I was getting confused with that as well.

Thanks in advance!
