Firing client from a local scirpt help?

I'm only doing this because I need to work around fe

error: 'FireClient can only be called from server Line 12'

I've tried a million times using everything I can to get this to work but to no avail.

--Sending/Reciving script

local Access = {"Adeleina","NotSoNorm","Player"}
local name = game.Players.LocalPlayer.Character.Name
local pos = "Inward"

if name == Access[1] or name == Access[2] or name == Access[3] then
    script.Parent.EditFrame.Visible = true
else
    script.Parent.EditFrame.Visible = false
end

script.Parent.EditFrame.Enter.MouseButton1Down:connect(function()
    game.Workspace.DisplayManger.Sender:FireClient(game.Players.LocalPlayer.Character, script.Parent.EditFrame.TextBox.Text)
end)

script.Parent.EditFrame.Hide.MouseButton1Down:connect(function()
    if pos == "Inward" then
        pos = "out"
        script.Parent.EditFrame.Hide.Text = "Hide"
        script.Parent.EditFrame:TweenPosition(UDim2.new(0, 0,0.4, 0),"InOut","Linear",.5,false)
        script.Parent.EditFrame.Hide:TweenPosition(UDim2.new(0,0,1.02,0),"InOut","Linear",.5, false)
    else
        pos = "Inward"
        script.Parent.EditFrame.Hide.Text = "Show"
        script.Parent.EditFrame:TweenPosition(UDim2.new(-.5, 0,0.4, 0),"InOut","Linear",.5,false)
        script.Parent.EditFrame.Hide:TweenPosition(UDim2.new(1.62,0,1.02,0),"InOut","Linear",.5, false)
    end
end)

game.Workspace.DisplayManger.Sender.OnClientEvent:connect(function(text)
    script.Parent.TextLabel.Text = "The party is at: "..text
end)
