Solved How to place blocks on variable list's locations?

[PantherBoy]

I did this code:

variables:
    {edit} = false
   
on skript start:
    loop 10000 times:
        wait 3600 seconds
        execute command "/magusfelho"

command /magusfelho [<text>] [<int>]:
    trigger:
        if arg 1 is "edit":
            if {edit} is false:
                set {edit} to true
                loop {magusfelhok::*}:
                    replace blocks on looped-locations to air
                broadcast "Edit started"
            else if {edit} is true:
                set {edit} to false
                set {magusfelhok::*} to air
                broadcast "Edit stopped"
        if arg 1 is "list":
            broadcast "%{magusfelhok::*}%"
        if arg 1 is "del":
            delete {magusfelhok::%arg 2%}
            broadcast "%arg 2% item deleted from the list"
       
on place of bedrock:
    if {edit} = true:
        broadcast "Block placed"
        set event-block to bedrock
        add location of event-blocks to {magusfelhok::*} 
       
on break of bedrock:
    if {edit} = true:
        broadcast "Block removed"
        set event-block to air
        remove location of event-blocks from {magusfelhok::*}

But I have a problem:
"Can' understand this condition/effect: replace blocks on looped-locations to air (line:15)"
How can I fix it?

loop {magusfelhok::*}:
    set block at loop-value to air
