Variable help

[CUrrUpt Enxo]

hmm yes variables

{playersgens::%player's uuid%::%{_tag}%::%location%}

You see that variable right ima explain what I need help with.
I want to find the {_tag} value according to a location but I want to do this without looping the index.
I don't even know if this is possible but if its not I will just loop.

here is a updated problem

if {playersgens::%player's uuid%::*} where [indices of input contains "%location of event-block%"] is set

Why wont this work with

set {playersgens::%player's uuid%::%{_tag}%::%location of event-block%} to location of event-block

this variable structure like what the heck
