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.
