[Threshold]

pawn Code:

new Float:BoughtSpawns[][3] =
{
    (132.0000,  -67.2844,   3.5781),
    (132.0000,  -67.2844,   3.5781),
    (132.0000,  -67.2844,   3.5781),
    (132.0000,  -67.2844,   3.5781),
    (132.0000,  -67.2844,   3.5781),
    (132.0000,  -67.2844,   3.5781),
    (132.0000,  -67.2844,   3.5781),
    (132.0000,  -67.2844,   3.5781),
    (132.0000,  -67.2844,   3.5781),
    (132.0000,  -67.2844,   3.5781),
    (132.0000,  -67.2844,   3.5781)
};
new BS[sizeof(BoughtSpawns)];

pawn Code:

for(new i = 0; i < sizeof(BoughtSpawns); i++)
{
    BS[i] = CreateDynamicPickup(1313, 1, BoughtSpawns[i][0], BoughtSpawns[i][1], BoughtSpawns[i][2]);
}

Also:

pawn Code:

public OnPlayerPickUpPickup(playerid, pickupid)
{
    for(new i = 0; i < sizeof(BoughtSpawns); i++)
    {
        if(pickupid == BS[i])
        {
            GameTextForPlayer(playerid, "~l~~h~DO ~g~/buyspawn ~l~~h~TO BUY THIS SPAWN!", 2000, 5);
        }
    }
    return 1;
}

I haven't worked with these in a while, but give it a shot and see if it works.
