So, i was making an coin to cash and cash to coin exchange but when i tried to get the number from the text box it says: "attempt to perform arithmetic (add) on number and string." even though i check if its a number when the exchange button is clicked, so i still dont get it... Can you help?

Scripts:

Exchange script (script, server script service):

01local cct = game.ReplicatedStorage.remoteEvents.exchange.cointocash
02local ccbt = game.ReplicatedStorage.remoteEvents.exchange.cashtocoin
03local txtbox = game.StarterGui.ccexhanfe.Frame.COIN.ccframe1.TextBox
04local st = game.ReplicatedStorage.ST

07cct.OnServerEvent:Connect(function(player, amntD, sta)
08    local thisplr = game.Players:findFirstChild(player.Name)
09        if (thisplr~=nil) then
10            local stats = thisplr:findFirstChild("leaderstats")
11            if (stats~=nil) then
12                local cash = stats:findFirstChild("Cash")
13                local coin = stats:findFirstChild("Coins")
14                if (cash~=nil) then
15                cash.Value = cash.Value + txtbox.Text
16                st.Value = "SUCCESS!"
17            end

Button script (local script, starter gui):

01local txtbox = script.Parent.Parent.TextBox
02local sta = game.ReplicatedStorage.ST

04local amntD = txtbox.Text

12        if tonumber(txtbox.Text) then
13            sta.Value = "WORKING ON IT!"
14            wait(3)
15            cct:FireServer(amntD, sta)
16        else
17            sta.Value = "Please enter a number!"
18        end
19end)

Dont judge me for using a StringValue, i will fix that soon, its just for test purposes. Also i tried the tonumber(txtbox.Text) that doesnt work either... it says: attempt to perform arithmetic (add) on number and nil

txtbox.Text is a String. Can't use it in math Spjureeedd 385 — 4y

And you're using StarterGui. Which is not correct actually. Read up about it. You should check the players' PlayerGui Spjureeedd 385 — 4y

Then how do i get the number VikkiVuk 74 — 4y

I tried the tonumber but that doesnt work either VikkiVuk 74 — 4y

Well you should use tonumber on the text. But you're getting the text the wrong way. Try sending it via the RemoteEvent Spjureeedd 385 — 4y

Ok, i will try that. I will let you know if it works or not. VikkiVuk 74 — 4y

Oh, it works!! Thank you! VikkiVuk 74 — 4y
