On right click on {var}:

[Cold]

I'm checking when a player is right clicking on a block a variable thats set to "black stained hardened clay"
It doesn't spit any errors, but it doesn't work and all code after it stops working.

I believe your issue could be that you had a small typo for the block type you're attempting to check for. The block type I think that you're trying to check for would be "black terracotta". You have to be careful with block types as any small error will cause it to fail to work. However, an FYI; I attempted testing usage of something like:

on right click on black stained hardened clay:
   send "test"

I did not get any errors with this code, but I would recommend swapping it out with "black terracotta" and proofreading your code carefully to see if there are any other issues present that would result in your code not working.

I have tested with using terracotta and did nothing.
I also have an command within skript that sends the name of the block so I can make sure its the right one I'm using, and it outputs black stained hardened clay?
