Argument #3 is nil

Help and Feedback Scripting Support
#1

I’ve tried figure out long as is was possible, but I’m still stuck with the issue.

Mainly I wanna make the UI that let’s players change amount of Apple if it’s lower then it should warn them.

Local script:

local changedValue, changedAmount, message =  changeApples:InvokeServer("changeApple,appleToPass")

elseif message == "Max Apple Pack" and changedAmount ~= nil then
appleLabel:WaitForChild("messageLabel").Text = message

Server:

Events.changeAppleRemote.OnServerInvoke = (function(plr,whichAction,changedAmount,message)
	if whichAction == "changeApple" then
		if type(changedAmount) == "number" then
			if changedAmount < 3 then
					whichAction = message
					if message then
						message = "Too low! Lowest Apple set"
					end
			end

appleToPass is amountBox.Text on UI

The problem is when I type anything it gets nil value instead string one(message)

perhaps you meant :InvokeServer("changeApple", tonumber(appleToPass))?
also you are not passing a message parameter but the server expects one.

#3

No since it works pretty good instead the server one

#4

The server code will error because you are passing the parameters incorrectly from the client.

#5

Yeah I am talking about the message one which is why I’m confused

#6 
		local changedValue, changedAmount, message = changeApples:InvokeServer("changeApple",appleToPass)
		if changedValue == true and changedAmount ~= nil then
			sound:Play();
			amountBox.Text = tostring(changedAmount);
			number = tostring(changedAmount);
			if i ~= nil then
				i:Cancel();
			end;
			messageLabel:WaitForChild("messageLabel").Text = message;
			messageLabel.messageLabel.TextColor3 = Color3.fromRGB(0, 255, 0);
			messageLabel.messageLabel.Visible = true;
			hm = ts:Create(messageLabel.messageLabel, TweenInfo.new(3), {
				Visible = false
			});
			i:Play();
			return;
		end;
		if message == "Max Apple set" and changedAmount ~= nil then
			sound:Play();
			amountBox.Text = tostring(changedAmount);
			test = tostring(changedAmount);
			if hm ~= nil then
				hm:Cancel();
			end
			messageLabel:WaitForChild("messageLabel").Text = message;
			messageLabel.messageLabel.TextColor3 = Color3.fromRGB(0, 255, 0);
			messageLabel.messageLabel.Visible = true;
			hm = ts:Create(messageLabel.messageLabel, TweenInfo.new(3), {
				Visible = false
			})
			hm:Play()
			return
		end

It’s the local, what’s wrong with it? It’s works perfect instead server side.

I will be grateful to anyone who could help me with this problem, I can’t understand it in any way after spending 1 hour on it.

The server is expecting a message. Get rid of that and the script should at least run since the 3rd argument is going to be nil since you provided no parameter value in line :

So change it to

local changedValue, changedAmount, message = changeApples:InvokeServer(“changeApple”, appleToPass, **YOUR MESSAGE GOES HERE as the server expects it**)

I tried do it as well and still nothing. The thing is server puts print on but not from client side.

#10

What and where on your code does the server return to those variables on the client?

#11 
		local appleToPass = tonumber(amountBox.Text)
		if appleToPass == nil then
			amountBox.Text = amountBox
			dSound:Play()
			return
		end
		local changedValue, changedAmount, message = changeApples:InvokeServer("changeApple",appleToPass)

1st = Server side, 2nd = local:

Did a very simple code to check what’s wrong and still nothing, there are the code of 1st screenshot:

You actually have to return the message variable in the server side and it should work

After the print statement, just do

return message

Works at the simple code that I was testing, but in mainly it’s still broken weird

#18

Did you add the return on the other ones as well? In their designated areas?

Thank you! I figured out and now fixed the my issue!

Good to hear, sorry I was at work!
