Attempt to concatenate string with Instance

[SubLimitless (Limitless)]

I keep getting an error on line 18 saying “Attempt to concatenate string with Instance”
Here is the script

local cameraInterpolateEvent = game.ReplicatedStorage.Remotes.cameraInterpolateEvent

local cameraToPlayerEvent = game.ReplicatedStorage.Remotes.cameraToPlayerEvent




for i, v in pairs(workspace.Triggers:GetDescendants()) do
	if v.Name == "Trigger" then
	triggernum = v.Parent.TriggerValue
v.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
	local player = game.Players:GetPlayerFromCharacter(hit.Parent)
		if player.MonsterJumpscared.Value == false then

			player.MonsterJumpscared.Value = true

					local monster = game.ReplicatedStorage.TriggersRep["Trigger" .. triggernum].monster:Clone()

			monster.Parent = game.Workspace

			monster.Head.Scream:Play()

					cameraInterpolateEvent:FireClient(player, game.Workspace.Triggers["Trigger" .. triggernum].CameraPosition.CFrame,game.Workspace.Triggers["Trigger" .. triggernum].CameraAim.CFrame,0.1)

			wait(1.25)

			cameraToPlayerEvent:FireClient(player)

					monster.Parent = game.ReplicatedStorage.TriggersRep["Trigger" .. triggernum]
			player.MonsterJumpscared.Value = false
		end
	end
end)
	end
	end

do you want to concatenate "Trigger" with triggernum’s name?

[SubLimitless (Limitless)]

triggernum is an intvalue and i want it to concatenate with the value

[SeargentAUS (Seargent)]

Then you’d want to do

"Trigger" .. tostring(triggernum.Value)
