it shows me what the next boost will be*

#152

and I want to make it so that it shows what a boost I have right now

#154

I always get this error after I buy a y class help fix my script and error

#155

Players.Lamino961.Backpack.Punch.AddStrength:18: attempt to perform arithmetic (mul) on number and nil - Client - AddStrength:18

#157

and it gives out this error in endurance, so this is the script

local cooldown = false
local player = game.Players.LocalPlayer
local addStat = game.ReplicatedStorage.AddStat
local getClassMult = game:GetService("ReplicatedStorage").RemoteFunctions.RetrieveClassMult

script.Parent.Activated:Connect(function()
	local End = player.Endurance
	local eZoneMulti = player.eZoneMulti
	local multi = player.eMulti.Value
	local fusionMult = player.BestFusion.FusionMulti.Value
	local classMult = getClassMult:InvokeServer()
	
	---------------------------------
	--        ADDING              --
	--------------------------------
	
	if cooldown == false then
		cooldown = true
		addStat:FireServer("Endurance", eZoneMulti.Value*classMult*fusionMult*multi, "+")
		script.Parent.Enabled = false
		wait(1.5)
		script.Parent.Enabled = true
		cooldown = false
	end
end)
#158

you can so that when the player buys the last class and at the end it wrote max like this is the maximum class

#159

The game is just ready to do it and that’s it

#160

Can you help add an abbreviation?

#161

You can abbreviate the classes by taking the first letter.

local a = className:sub(1,1)
#162

And where to write it in what line?

#163

I don’t know where it should be, but I think it should be in the function. But it was an example.

#164

I see, thank you, but you can help, I have a problem when I buy a class of 3 classes, my tools start to not work

#165

It gives an error and does not pump, can you help fix it?

#166

I think that is from the tool script, what is the tool script?

#167

my endurance script

local cooldown = false
local player = game.Players.LocalPlayer
local addStat = game.ReplicatedStorage.AddStat
local getClassMult = game:GetService("ReplicatedStorage").RemoteFunctions.RetrieveClassMult

script.Parent.Activated:Connect(function()
	local End = player.Endurance
	local eZoneMulti = player.eZoneMulti
	local multi = player.eMulti.Value
	local fusionMult = player.BestFusion.FusionMulti.Value
	local classMult = getClassMult:InvokeServer()
	
	---------------------------------
	--        ADDING              --
	--------------------------------
	
	if cooldown == false then
		cooldown = true
		addStat:FireServer("Endurance", eZoneMulti.Value*classMult*fusionMult*multi, "+")
		script.Parent.Enabled = false
		wait(1.5)
		script.Parent.Enabled = true
		cooldown = false
	end
end)
#168

error

Players.Lamino961.Backpack.Punch.AddStrength:18: attempt to perform arithmetic (mul) on number and nil - Client - AddStrength:18

#169

and script strength


local cooldown = false
local player = game.Players.LocalPlayer
local addStat = game.ReplicatedStorage.AddStat
local getClassMult = game:GetService("ReplicatedStorage").RemoteFunctions.RetrieveClassMult

script.Parent.Activated:Connect(function()
	local zoneMulti = player.ZoneMulti
	local multi = player.Multi.Value
	local fusionMult = player.BestFusion.FusionMulti.Value
	local classMult = getClassMult:InvokeServer()
	
	---------------------------------
	--        ADDING              --
	--------------------------------

	if cooldown == false then
		cooldown = true
		addStat:FireServer("Strength", zoneMulti.Value*classMult*fusionMult*multi, "+")
		script.Parent.Enabled = false
		wait(1.5)
		script.Parent.Enabled = true
		cooldown = false
	end
end)
#170

I think the problem is from the getClassMult, what is the script that manages it on the server?

#171 
func.OnServerInvoke = function(player)
	local class = player.Class
	local mults = require(game.ServerStorage["classMults"])
	
	local classMult
	if class.Value == "F-Class" then
		classMult = mults.fClass
	elseif  class.Value == "D-Class" then
		classMult = mults.dClass
	end
	
	return classMult
end
#172 
func.OnServerInvoke = function(player)
	local class = player.Class
	local mults = require(game.ServerStorage["classMults"])
	
	local classMult
	if class.Value == "F-Class" then
		classMult = mults.fClass
	elseif  class.Value == "D-Class" then
		classMult = mults.dClass
	end
if not classMult then warn("no classMult, default to 1") classMult = 1 end
	
	return classMult
end

Try that.
