pawn Code:

#include <a_samp>

#define valor (20)
new valores;

public OnFilterScriptInit()
{
    valores = valor; //warning 204: symbol is assigned a value that is never used: "valores"
    return 1;
}

public OnPlayerConnect(playerid) //Ejemple
{
    GivePlayerMoney(playerid, 2*valores); //<------
    return 1;
}
