Problem with vehicle system

[John]

Hi, the vehicle system that im using is showing null when I Enter vehicle instead of showing Owner's name and cost etc. Vehicle Entered: Infernus. Cost: (null : 0x(nil)). Owner: (null : 0x(nil)). Shares: (null : 0x(nil)) & (null : 0x(nil)).

Here is the code,

hy sorry for the bump but im getting this bug

today i was learning sql and this topic came to my notice. Running through the codes, i think the problem is in onPlayerEnterVehicle

local veh = player.Vehicle;
local q = QuerySQL( Vehicles, "SELECT * FROM Sale WHERE ID='"+veh.ID+"'" );

you have used veh.ID

hope this helps somebody
