My TeamChange GUI still does not work. Can you guys correct my code or something?

Alright so I posted this: https://scriptinghelpers.org/questions/63036/team-change-gui-textbuttons-are-only-working-in-studio-any-help (You should see the link above before answering here) And it did help me alot, but now that ive put FE its been a bit of a struggle. I have this ServerScript in the SSS that activates whenever the texbutton is clicked for a newTeam. I also have remoteEvent in the ReplicatedStorage. When I run the code im about to show you, I get this error:

FireEvent is not a valid member of RemoteEvent

This is my code(in the serverScript):

local remote = game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvent")
game.Players.PlayerAdded:Connect(function(Player)
	local TeamChangeGUI = Player.PlayerGui:WaitForChild("TeamChangeGUI")
	
	
	Player.PlayerGui.TeamChangeGUI.Frame.Blue.MouseButton1Click:Connect(function()
	local NewTeamName = "Blue"
		remote:FireEvent(NewTeamName)
	end)
	
	
	Player.PlayerGui.TeamChangeGUI.Frame.Blue.MouseButton1Click:Connect(function()
	local NewTeamName = "Red"
		remote:FireEvent(NewTeamName)
	end)
	
end)

And this is my code in the TextButton, it is a local-script and I have another one with the exact same code in the other TextButton(if that matters):

local player = game.Players.LocalPlayer
local Remote = game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvent")

Remote.OnServerEvent:Connect(function(Player, NewTeamName)
    local newTeam = game.Teams:FindFirstChild(NewTeamName)
    if newTeam then
        Player.Team = newTeam
        workspace[Player.Name]:BreakJoints()
    end
end)

FireEvent is not a thing. You're gonna want to use remote:FireServer() if you trying to fire a server script and remote:FireClient() or remote:FireAllClients() depending on what you want to happen. First one is for one specific player and the other is for all players.
