Hey all ![Smiley](images/smilies/smile.png)
I have this command
and it sells a car owned by a player to other /venderveiculo ID MONEY, but my problem is that the players can sell with negative values and the player who buy the car wins the money which was negative.
Example:
/venderveiculoplayer 0 -1000000
ID 0 wins 100000$ and ID 1 (seller) wins 0.
How can I prevent it?
