Hi,

I have 60 blocks where each question consist of four elements: Question-> Timer -> Follow up question -> Timer.
30 of the blocks are target items and the other 30 are lure items.
I want to present 15 target items and 15 lure items together for a recognition phase in random, I've attached a screenshot of my survey flow, any help would be so grateful!

@AliceWinsor,

Here is one way I think it could be done:
1. In a block prior to your randomizer, create a MC question with a choice for each of your 30 target items. Use Advanced Randomization to evenly select 15. Hide the question with JavaScript (`jQuery("#"+this.questionId).hide();`).
2. Create another question just like the above for each of your 30 lure items.
3. Put all your target and lure blocks under one randomizer and present all 60 items
4. Create a branch for each target/lure block (put the target/lure block under the branch). The branch condition should be if the target/lure was displayed in the applicable hidden question you created in step 1 and 2 above.
