Having trouble getting RemoteEvents to check BoolValue?

Hello,

I have an FE-compatible gun script that works as is, thanks to the wonderful AlvinBloxx. But what I'd like for it to do is to change the amount of damage dealt, based on if certain BoolValues are set to true or not.

For example, what I'd love for it to be able to do is:

if player.Upgrades.HasRed.Value == true then
damage = 50
else if player.Upgrades.HasBlue.Value == true then
damage = 75
--etc.

The way the BoolValues are set is that neither can be true at once. But I realize I probably need to use a RemoteEvent for this, and I'm doing it wrong. :D I've read the Wiki, and hiimgoodpack's tutorial: https://forum.scriptinghelpers.org/topic/186/how-and-when-to-use-remoteevents-and-remotefunctions and these things are confusing.

I'm not getting any error outputs here, and the damage being dealt is not consistent.

Here's how my broken portion of the script is currently:

local serverStorage = game:GetService("ServerStorage")
local replicatedStorage = game:GetService("ReplicatedStorage").GunRemotes
local checkBoolValue = replicatedStorage:WaitForChild("CheckBoolValue")
local KOValue = "Kills"
local WOValue = "Wipeouts"



--Function to check BoolValues and establish Damage
checkBoolValue.OnServerEvent:Connect(function(player,value)
	local Item1 = player.Upgrades:FindFirstChild("HasRed")
	local Item2 = player.Upgrades:FindFirstChild("HasBlue"')
	if Item1.Value == true then
		damage = 50
	elseif Item2.Value == true then
		damage = 80
	elseif Item1.Value and Item2.Value == false then
		damage = 25
				
	end
end)

--Rest of Gun Script below

If there's a better way to do this, with or without using RemoteEvents, I'm all for it. Thank you. :)

if Bool1.Value and Bool2.Value then -- check for both values as true.
	print("Both values true!")
elseif Bool1.Value then -- setting 1
	Damage = 80
elseif Bool2.Value then -- setting 2
	Damage = 50
else
	Damage = 25 -- no other possible combinations, neither are on.
end

EDIT: If your results are inconsistent, consider looking at the scripts that fire the remote events. No way to do it without remote events, unless you want hackers.
