Your code is compiling at my computer without any errors at all (with my own FreezeVehicle function),

Can you give us more information, like at which line this error occurs (and which code is at that line) ?

The error itself basicly means that you are trying to use invalid parameters on a function,

Example:

GOOD:

pawn Код:

public OnPlayerConnect(playerid)
{
    return 1;
}

WRONG:

pawn Код:

public OnPlayerConnect(playerid,param2much) //different parameters!!
{
    return 1;
}

pawn Код:

public OnPlayerConnect(vehicleid) //wrong parameter!!
{
    return 1;
}
