GetPlayerMoney. You should really use server-sided money though, to prevent the use of cheats.

i hope for this help you

if(GetPlayerMoney(playerid) < 500)
{
SendClientMessage(playerid, COLOR_RED, "You don't have enough money($500)");
}
if(GetPlayerMoney(playerid) > 500)//get's the player's money
{
GivePlayerMoney(playerid, -500);
}
}

1. Why two if statements? Why not use else or even better, return?
2. Use PAWN tags (both of you!)
3. Indentation - heard of it?
4. Nothing will happen if the player has exactly $500.

if(GetPlayerMoney(playerid) < 500) return SendClientMessage(playerid, COLOR_RED, "You don't have enough money ($500).");
// Code for giving weapon here
