So, what did I do wrong here?

Okay, so I have a wall that only allows certain teams to enter. I want the script to pop a message if the other team goes and touches the wall. The killing of the the other team works, and the transparency and everything works, but the message does not. Can someone help me with this? I only want the message going to that one person who was trying to go through that door/wall

Thanks here is what i have!

Door = script.Parent 
------------------------------------
modelname="Taxi Driver"
------------------------------------
 
function onTouched(hit) 
        print("Door Hit") 
        local human = hit.Parent:FindFirstChild("Humanoid") 
		local message = Instance.new("Message")
		message.Parent = game.Players:playerFromCharacter(hit.Parent)
        if (human ~= nil ) then
                if game.Players:playerFromCharacter(hit.Parent).TeamColor==game.Teams:findFirstChild(modelname).TeamColor then
                        Door.Transparency = 1
                        wait(1) 
                        Door.CanCollide = false 
                        Door.Transparency = 1 
                       
                else
                        human.Health = 0 
						message.Text = "Player was not a Taxi Driver" 
						wait(5) 
						message:Remove ()

                end
 
        end 
end 
 
connection = Door.Touched:connect(onTouched)

local debounce = false

Problem

The message is not showing up.

Solution

You put the message in the player. You should put it in the PlayerGui to be client-sided.

Suggestions

playerFromCharacter is deprecated, meaning it is unfavorable but still fully functional., use GetPlayerFromCharacter. Also, remove the "connection" variable and just keep it as Door.Touched:connect(onTouched). :findFirstChild was changed to capitalize to :FindFirstChild. Local variables are also in favor to stop lag. You can also parent a new instance by adding it, like this: Instance.new("Part", workspace). And the debounce is not there in the beginning so I'll fix that. This is all very outdated.

Final Script (w/ Suggestions)

local Door = script.Parent 

debounce = false

local modelname="Taxi Driver"

function onTouched(hit) 
        print("Door Hit") 
        local human = hit.Parent:FindFirstChild("Humanoid") 
       local message = Instance.new("Message", game.Players:GetPlayerFromCharacter(hit.Parent).PlayerGui)
        if (human ~= nil ) and (debounce == false) then
if game.Players:GetPlayerFromCharacter(hit.Parent).TeamColor==game.Teams:FindFirstChild(modelname).TeamColor then
			debounce = true
                        Door.Transparency = 1
                        wait(1) 
                        Door.CanCollide = false 
                        Door.Transparency = 1 
                else
                        human.Health = 0 
                        message.Text = "Player was not a Taxi Driver" 
                        wait(5) 
                        message:Remove()
                end
        end 
end 

Door.Touched:connect(onTouched)

debounce = false
