[MC-117730] /function not working... at all

Function command dosn't work

so what i thought would work is a function to put barriers in all the slots except the hot-bar

what managed to happen was it giving an error that it wasn't found

steps i took was 1.make a function the specific function was this
#barrier

the second thing i did was save it in the functions folder in the data folder of the world i was put it in a folder i made named "survival" (its not a zip folder) inside the functions folder inside the data folder and named my function command barrior.mcfunction

the third thing i did was type /reload then i typed /function survival:barrior

it came up with an error saying that there was no function so i went off my world came back on it did the same i as well typed /function survival:barrior.mcfunction and still nothing worked

if this is not a bug but something i did wrong then please tell me.
