Is there a function that check if already exists a Data in a account?

[Castillo]

just do,

data = getAccountData(account,"my_data") 
if data then 
outputChatBox("Data is exist") 
else 
outputChatBox("Data doesn't exist") 
end

What Solidsnake14 wrote works fine, you probably copied it wrong, show us your code

[Castillo]

you don't have argument "account" i'm guessing, as SDK said show us your code.

i don't use that code, but can you fix this?

local paccount = getPlayerAccount(player) 
if getAccountData(paccount, "msprpg.license") == 0 then 
introduzione () 
end

show us your whole code, where you get the player element, etc.
