Apologies if this ends up being a silly issue.
I am currently trying to program part of a task and having a strange issue I cannot work out. I have four sets of stimuli items that make up the total set of stimuli items across the task. In this task there are four identical (at least for the purpose of this explanation) blocks, thus in every block the set of stimuli items is drawn from one of the four sets of stimuli items. I want the set of item for each block to be chosen randomly such that the order of sets of stimuli items is random but every participant sees all four sets of stimuli items once and only once.
I will include the relevant code below to provide further clarification, but my approach so far has been to set a <value> based on a <list> of the different possible item sets at the beginning of each <block>, I then, use a series of IF statements to check what the <value> is set to, and add the corresponding items from that specific item set to two general <item> elements such that they may be drawn upon to create the stimuli for that block. At the end of each block I then clear the general <item> elements.
My issue is that whilst one of the general <item> elements seems to be correctly filling with the items from the correct item set, the other general <item> element fills with items from the first set (first in regard to the order it appears within the series of IF statements). I cannot work out why this is happening, whether it is a simple mistake on my part or rather a misunderstanding of how Inquisit works. My apologies if anything is unclear as I am rather new to Inquisit so am trying to make things as clear as possible but may be missing crucial information. Regardless, as mentioned before I will include the relevant code below and any help would be greatly appreciated.

Apologies as well for the length, I have tried to exclude everything irrelevant but please let me know if there is anything else required and any help is greatly appreciated.
Cheers.
