Save location block

[Zuixik]

How do I save the location of the block but then it could not be destroyed? 

Here is the script but it does not work. I don't know how to fix it

1.  

   on break:
       {crates::NAME::locations*} is set
       {crates::NAME::locations*} contains location of event-block
       add 1 to {crates::NAME::progress}
       cancel event
       # play sound
   
   command /crate <string>:
       trigger:
           add location of target block to {crates::%argument 1%::locations::*}
           message "added crate %argument 1%"
