External functions Error Missing function binding for external

[pixitales]

on ink file I wrote this on the very top: EXTERNAL PlaySound(name)

My fallback ===function PlaySound(name)=== ~ return

to call the function I wrote {PlaySound("SlipFall")}

and Unity gives me an error: ERROR: Missing function binding for external: 'PlaySound' , and no fallback ink function found. Im using Unity 2021 LTS. Anyone know how to fix?

oh nvm i fixed it, i guess the timing was wrong in my c# script. Need to be bind right after the ink story is created
