Help, there's a error in my function and I dunno how to fix it

[pliant socket]

execute as @e[type=thebrokenscript:null_miner] at @s run damage @a 6 [r=3]
execute as @e[type=thebrokenscript:null_miner] at @s run playsound youwillbecomeoneofus @a[r=3]
execute as @e[type=thebrokenscript:null_miner] at @s run kill @s[r=3]

[Commands][warning]-Function null_miner failed to load correctly with error(s):

[Commands][warning]-Error on line 1: command failed to parse with error 'Syntax error: Unexpected '[': at 'amage @a 6>>[<<r=3]''

Idk if this is different in functions but why did you write as at for some of these instead of just at

Also read the errors it says you wrote it wrong

It’s at @s run damage @a[r=3] 6

You can’t not attach the arguments to the selector if you do they’re meaningless

Also idk if this is intentional but is it supposed to kill itself in the last command
