AlliedModders - AWP Automatically on awp maps and change the price

Hello,i need help :( i have a respawn server and awp is restricted,i have this plugin on him but i want to change the price in 5000$ or another price for awp and doesen't work! good,that is the first problem :)) ...second problem: on all maps awp is restricted,actually awp cost 15000$ in this moment,i want to know how can i give free awp on awp maps only?

The code for my first problem,where i want to change the price in 5000$:

Quote:

#include <amxmodx>
#include <cstrike>
#include <fun>

new g_pCvar_Price;

public plugin_init()
{
register_plugin("Buy AWP", "0.0.1", "dinnk.");

register_clcmd("say /awp", "CmdAwp");

g_pCvar_Price = register_cvar("awp_deagle_price", "15000");
}

public CmdAwp(id)
{
new iMoney = cs_get_user_money(id);
new iPrice = get_pcvar_num(g_pCvar_Price);

if( !is_user_alive(id) )
{
client_print(id, print_chat, "* You need to be alive !");
return PLUGIN_HANDLED;
}

if( iMoney < iPrice )
{
client_print(id, print_chat, "* You need more money ! ($%i)", iPrice);
return PLUGIN_HANDLED;
}

give_item(id, "weapon_awp");
give_item(id, "weapon_deagle");
cs_set_user_bpammo(id, CSW_AWP, 30);
cs_set_user_bpammo(id, CSW_DEAGLE, 35);

client_print(id, print_chat, "* You bought an AWP & Deagle for $%i !", iPrice);
cs_set_user_money(id, iMoney - iPrice, true);
return PLUGIN_HANDLED;
}

Edit:i forgot something ;)) i change it the price in 5000$ and i compiled again but doesen't work!
