Kill all players and then change their team script?

So I've been trying to get this to work all day. I am seething with rage right now. I am ready to launch my game, but cannot because of this. I need it to work once a brick is clicked. I made the part, put the click detector in it, and this is the bit of the script I already have:

function ClickTime(Plyr)
for i,v in pairs(Players:GetPlayers()) do
v.Character:BreakJoints()
end
end
script.Parent.ClickDetector.MouseClick:connect(ClickTime)

However, that didn't work, and It didn't change the teams(Because I still don't know how to do that). So then I tried this:

local detect = script.Parent.ClickDetector -- Assuming the script is within a part, and the part has a ClickDetector in it

function kill()
        for i, v in pairs(game.Players:getPlayers()) do
        v.Character:breakJoints()
end

detect.MouseClick:connect(kill)

And that didn't work either. If someone can help me make these scripts kill all, that would be great. And if you need to know the teams, they are: "Really red" "Bright blue" "Bright yellow" And I am trying to change the teams to yellow.
