[YesYesYes]

I know I shouldn't, but let me tell you some bullshits in your filterscript

1. You have all the callbacks in it, which are just not needed, remove all of them.

2. You didn't even #define FILTERSCRIPT, its a gamemode..!!

3. I see some shits like this-

pawn Code:

if(GetPlayerMoney(playerid) < 500) return SendClientMessage(playerid, 0xFF0606AA, "You need $2500 dollars in order to use this command!");

4. Giving player money after repair, seriously?

pawn Code:

GivePlayerMoney(playerid, 2500);

5. I instantly said WTF after watching this-

pawn Code:

SendClientMessage(playerid, 0xFF0606AA, -1, "Your vehicle has been sucessfully repaired!");

pawn Code:

SendClientMessageToAll("0xFF0606AA, %s just use /repairveh and paid $2500!");

you need to format string, and use %s in that..!
also, how the hell you can use 4 parameters in SendClientMessage.

please, don't post FS if you are still learning, it also misleads other newbies
