How I can check if all players of selected team are dead

[DragonAce]

Hello guys, I've started researching Skript one week ago and I have some problems that I can't solve
So, what code I have right now
on death:
if {round_active} is true:
if all players where [team of player is "t"] are dead:
broadcast "T team is dead! CT wins!"
add 1 to {ct_score}
execute command "/endround"
else if all players where [team of player is "ct"] are dead:
broadcast CT team is dead! T wins!"
add 1 to {t_score}
execute command "/endround"

And I always recieving this error

[14:12:06 INFO]: Can't understand this effect: else[14:12:06 INFO]:
Line: else if all players where [team of player is "ct"] are dead:

What I can do with this?
P.S: MC version 1.20.1 and latest stable version of Skript - 2.11

on death:
    if {round_active} is true:
        if {blue::*} contains victim:
            remove victim from {blue::*}
            loop all players in {blue::*}:
                set {blueplayers::*} to loop-player
                set {blueplayersleft} to amount of {blueplayers::*}
                if {blueplayersleft} is 0:
                    #end game
        else if {red::*} contains victim:
            remove victim from {red::*}
            loop all players in {red::*}:
                set {redplayers::*} to loop-player
                set {redplayersleft} to amount of {redplayers::*}
                if {redplayersleft} is 0:
                    #end game

This is from my proximity chat skript. Hope it works!
Note: Put your end code at "#endgame"
