Jetpack Help..

Hello, I tried to write a code that would give Jetpack to everyone with sound and screen shaking, but something didn't work, if someone can help, here is the code:

public Command_Jetpack1(iPlayer)
{
new iPlayers[ 32 ], iPlayersNum;

get_players( iPlayers, iPlayersNum, "ach" );


static i;
static iJetpacks[33];
static iDistance;
iJetpacks[iPlayer] ++;

if( iPlayersNum == 0 )
{
PrintToChat(iPlayer, "^4[ZP]^1 No Players Online.")

return 0;
}



if (is_user_alive(iPlayer))
{

for( new i = 0; i < iPlayersNum; i++ )

for ( i = 1; i < g_iMaxClients + 1; i ++ )

if (get_user_jetpack(iPlayer))

{

user_drop_jetpack(iPlayer, 1);

}

set_user_jetpack(iPlayer, 1);

set_user_rocket_time(iPlayer, 0.0);

set_user_fuel(iPlayer, 250.0);

send_screen_shake(i, (75000<<1) , (12500<<1), (67500<<1));

send_screen_fade(i, 255, 0, 0, iDistance < 220 ? 220 : 160);

client_cmd(i, "spk sound");

new szname[32]

get_user_name(iPlayer,szname,31)

set_hudmessage(205, 92, 92, 0.03, 0.5, 0, 20.0, 6.0, 0.1, 0.2, false);

ShowSyncHudMsg(0, g_iEventsHudmessage, "ADMIN %s Has give JetPack to everyone playing!", szname);

PrintToChat(iPlayer, "^4[ZP]^1 ADMIN^4 %s^1 has give a^3 JetPack^1 to everyone playing.", szname);
}
return 0;
}
