number of players in specific gamemode

[Stefqnutz]

ik it sounds simple but i wanna make it so that it basically checks the gamemode of the amount of all players on the server in a specific world
i tried using "number of players in world x" and while it works, i cant check the for the gamemode
loops are also not gonna work since if i do this:
loop all players:
if loop-player's gamemode is spectator:
if loop-player is in world "world":
add 1 to {spectators}

it will constantly increment the value.
so what can i do?

command /worldmode [<text>] [<player>]:
    trigger:
        player's world is "%arg-1%":
            if gamemode of arg-2 is survival:
                add player to {Survival::*}
                send "You have been added to survival" to arg-2

You can thank me later
