Well first, PriceInRobux is nil in your case so doing
Cost.Text = "R$"..Price
is same as doing
Cost.Text = "R$"..nil
It can't work, to get PriceInRobux without it being nil you need to change line 7 from Enum.InfoType.Product to Enum.InfoType.GamePass so
local ProductInfo = MarketplaceService:GetProductInfo(ID, Enum.InfoType.GamePass)
Now it will get your PriceInRobux, but it will still error that you are trying to compensate number with string because
Cost.Text = "R$"..Price
is same as
Cost.Text = "R$"..300 -- for example
Which you also can't do, to fix this you can use 2 ways. First way is tostring:
Cost.Text = "R$"..tostring(PriceInRobux)
Which will convert given value into string. The second way is using string.format:
Cost.Text = string.format("R$ %d", PriceInRobux)
About string patterns here, Basically %d is pattern for numbers so it takes second argument which is PriceInRobux and formats it into the %d pattern so the result should be R$ 300 (Not 300 but PriceInRobux). This might not work as i have no idea what i am doing i haven't used MarketplaceService since 2019. If it did not help, don't accept it as an answer.
