Pseudorandomly present blocks

Hello nickname,
You can include all the blocks under a Randomizer as shown below and click on Evenly present elements. I hope this solves the issue. Kindly read this support page as well for more information.
Hope this solves the problem.

RandomizerLinking it again.

Hi Deepak, thanks for getting back to me so soon.
The problem I'm having is setting up the survey flow that it shows a "breather block" to the subject after answering every 30 question blocks while keeping the randomizer.
so like Q-Q-Q(30 blocks) -- "breather1" -- Q-Q-Q(30 blocks) -- "breather2" -- so on...
I tried having 3 separate randomizer element with all 100 blocks, have it present 30 at a time with evenly present element box checked, but the issue here was the second and third randomizer showed question blocks that were already shown.
Hope this clears things up a bit.
Thank you so much!
Erin.

Hello,
You can include 3 breathers with 4 randomizers, what I mean here is :
**Presuming that you are including 100 blocks after each randomizer
Workaround: A set of 25 blocks in each randomizer and then a breather so it wouldn't repeat in the randomizers below.
QQQQ(25 blocks only below the randomizer)..breather1...Seperate1 25 blocks randomizer.. breather2..Seperate2 (25 blocks randomizer).. breather3..(Seperate4 25 blocks randomizer)
With evenly present elements checked. This should solve your issue of blocks being shown again.

Thank you so much TomG and Deepak!
