I'm using string.sub, but my output says "Invalid Argument #1 to "sub". What do I do?
I'm trying to make a "Skip Stage" in my Obby, but my output says
"invalid argument #1 to 'sub' (string expected, got Instance)"
The code:
01 | local MarketplaceService = game:GetService("MarketplaceService")--The Service |
02 | local Players = game:GetService("Players")--More Services |
03 |
04 | local productID = 1083524533--Product ID |
05 |
06 | local function promptPurchase()--The function |
07 | local player = Players.LocalPlayer--The Player |
08 | MarketplaceService:PromptProductPurchase(player, productID)--Prompt it |
09 | MarketplaceService.PromptProductPurchaseFinished:connect(function()--When it's done |
10 | local stage = script.Parent.Parent.Parent.Parent.Parent.Team--The Team(From Alvin_Blox) |
11 | print(string.sub(stage,6,7))--this doesn't work |
12 | end)--end |
13 | end--end |
14 |
15 | script.Parent.MouseButton1Click:Connect(promptPurchase)--Connect it |
I got the script from the Developer Hub, The PromptProductPurchaseFinished from the Developer Forum, the Teams Stuff from Alvin_Blox, and the string.sub from Scripting Helpers.
Edit: I'm just testing it but the real problem is so it will teleport a player to the next spawn location's position.

The string.sub() on its first parameter it needs a string value,The thing you inserted is a model,models are instances
01 | local MarketplaceService = game:GetService("MarketplaceService")--The Service |
02 | local Players = game:GetService("Players")--More Services |
03 |
04 | local productID = 1083524533--Product ID |
05 |
06 | local function promptPurchase()--The function |
07 | local player = Players.LocalPlayer--The Player |
08 | MarketplaceService:PromptProductPurchase(player, productID)--Prompt it |
09 | MarketplaceService.PromptProductPurchaseFinished:connect(function()--When it's done |
10 | local stage = script.Parent.Parent.Parent.Parent.Parent.Team--The Team(From Alvin_Blox) |
11 | print(string.sub(stage.Name,6,7)) |
12 | end)--end |
13 | end--end |
14 |
15 | script.Parent.MouseButton1Click:Connect(promptPurchase)--Connect it |
The second parameter of it,it tells in where character to start
1 | string.sub("MyString",3,7) |
m(1)y(2)s(3) It means that the string.sub will start in the "S" character and it will be "String"
And the last parameter that is optional,it tells where to stop,in this case it is a seven it will be: "Strin"
The string.sub,is basically a string cutter.
Hope it helps!
