Can't Compare 'spawner's set name' with a text

[ArthurMorgan]

Hello, I am trying to make a script where if a player broke a spawner, it drops with the spawn egg of the mob inside it, but I get the error:

Can't compare 'spawner's set name' with a text (spawner.sk, line 11: if spawner's set name is "blaze":')

My code:
on right click:
if clicked block is spawner:
if player's held item is blaze spawn egg:
set name of spawner to "blaze"


on break of spawner:
if spawner's set name is "blaze":
drop 1 blaze spawn egg and 1 spawner

it wont work like that, since the spawner does not have a gui It wont set a name if its placed down because it has no where to save it

you can add a custom nbt to that block but it would be deleted once you restart the server
