Does anyone know anything about getting info on a gui element to only show once?

I have been having trouble for the past week, here's how far i got before actually coming here to ask for help.The reason why i am here is because to get help on how to make sure it only displays some info once, and not over and over again.

This LocalScript handles everything to do with the player's GUI. In this case the event bar, which displays information on the player's screen, such as who killed who with what.

local Main = script.Parent.Parent.PlayerGui.Main
local BattleUI = script.Parent.Parent.PlayerGui.BattleUI
local LoTrig = game.ServerStorage.LoTrig


----|----- EventBar -----|----
local EventBar = BattleUI.EventBar
local View = BattleUI.EventBar.View
local Bar = BattleUI.EventBar.View
local Bar1 = View.Bar1
local Bar2 = View.Bar2
local Bar3 = View.Bar3
local Bar4 = View.Bar4
local Bar5 = View.Bar5
local On1 = Bar1.On
local On2 = Bar2.On
local On3 = Bar3.On
local On4 = Bar4.On
local On5 = Bar5.On


function EventFrameDisplay(K, D, Wep)--Way  

    local LastKill = K
    local LastDeath = D 
    local LastWeapon = Wep


    if Bar1.Weapon.Text == "NaN" and On1.Value == false then

        On1.Value = true


    elseif Bar2.Weapon.Text == "NaN" and On2.Value == false then

        On2.Value = true



    elseif Bar3.Weapon.Text == "NaN" and On3.Value == false then

        On3.Value = true



    elseif Bar4.Weapon.Text == "NaN" and On4.Value == false then

        On4.Value = true



    elseif Bar5.Weapon.Text == "NaN" and On5.Value == false then

        On5.Value = true

    end

    if On5.Value == true then

        Bar5.Killer.Text = K
        Bar5.Killed.Text = D
        Bar5.Weapon.Text = Wep
        Bar5.Visible = true
        wait(4)
        Bar5.Visible = false
        Bar5.Weapon.Text = "NaN"
        On5.Value = false

    end

    if On4.Value == true then

        Bar4.Killer.Text = K
        Bar4.Killed.Text = D
        Bar4.Weapon.Text = Wep

        Bar4.Visible = true
        wait(4)
        Bar4.Visible = false
        Bar4.Weapon.Text = "NaN"
        On4.Value = false

    end

    if On3.Value == true then

        Bar3.Killer.Text = K
        Bar3.Killed.Text = D
        Bar3.Weapon.Text = Wep

        Bar3.Visible = true
        wait(4)
        Bar3.Visible = false
        Bar3.Weapon.Text = "NaN"
        On3.Value = false

    end

    if On2.Value == true then

        Bar2.Killer.Text = K
        Bar2.Killed.Text = D
        Bar2.Weapon.Text = Wep

        Bar2.Visible = true
        wait(4)
        Bar2.Visible = false
        Bar2.Weapon.Text = "NaN"
        On2.Value = false

    end

    if On1.Value == true then

        Bar1.Killer.Text = K
        Bar1.Killed.Text = D
        Bar1.Weapon.Text = Wep

        Bar1.Visible = true
        wait(4)
        Bar1.Visible = false
        Bar1.Weapon.Text = "NaN"
        On1.Value = false

    end

    if Bar2.Killer == Bar1.Killer and Bar2.Killed == Bar1.Killed and Bar2.Weapon == Bar1.Weapon then

        Bar2.Visible = false
        print("OK")
    end


    --[[Bar.Killer.Text = K
    Bar.Killed.Text = D
    Bar.Weapon.Text = Wep

    Bar.Visible = true
    wait(4)
    Bar.Visible = false --]]


end


LoTrig.Event:connect(EventFrameDisplay)

while true do 

wait(3)
LoTrig:Fire(LaLa, Land, AGun)

end 

-- if that doesn't work, then cancel while true do statement and use the one below.

--[[
    LoTrig.Fire(LaLa, Land, AGun)

--]]

This LocalScript is used to fire an event that triggers the function, EventFrameDisplay. This method is used on my custom gun; to fire the LoTrig Event, which in turn, triggers the function that displays the information.

hitHumanoid = findFirstClass(H.Parent, "Humanoid")

            if hitHumanoid and hitHumanoid.Health > 0 and isEnemy(hitHumanoid) then
                local Tag = Instance.new("ObjectValue")
                Tag.Value = Player
                Tag.Name = "creator"
                Tag.Parent = hitHumanoid
                DS:AddItem(Tag, 0.3)
                local chosenDamage = 0
                if H.Name == "Head" then
                    chosenDamage = baseDamage  * RAND(hVal, hVal + 0.1, 0.01)
                elseif H.Name == "Torso" then
                    chosenDamage = baseDamage  * RAND(cVal, cVal + 0.1, 0.01)
                else
                    chosenDamage = baseDamage  * RAND(lVal, lVal + 0.1, 0.01)
                end
                hitHumanoid:TakeDamage(chosenDamage)
                markHit()
            elseif hitHumanoid and hitHumanoid.Health == 0 and isEnemy(hitHumanoid) then
                -- the event fires under this conditional.
                LoTrig:Fire(Player.Name, hitHumanoid.Name, script.Parent.Name)

            end

I have gotten it to work on the previous attempts, but it kept on sending information over and over like this if ran. The event was fired through my own custom gun, but i'll just leave an trigger within the script

This was put into a local script that was placed in game.StarterPlayer.StarterPlayerScripts.

Any answer related to this will be greatly aprecciated.

And if needed, you may ask for the gun script. Here's an piece.

EDIT: Forgot to include the link to the ui.
