Hello, I am in need of some help, I have made an announce script, but I want it to work with Ladmin4v2, I have the include, but every time I try to compile it, I get 1 error and 1 warning I can't fix.

Code:

C:\Documents and Settings\Administrator\Desktop\AnnounceScript1.pwn(9) : error 017: undefined symbol "cmd"
C:\Documents and Settings\Administrator\Desktop\AnnounceScript1.pwn(11) : warning 204: symbol is assigned a value that is never used: "cmd"

I am a new coder, so I have tried to do this:

Code:

#include <a_samp>
#include <isplayerLadmin>
#include <core>
#pragma tabsize 0


public OnPlayerCommandText(playerid, cmdtext[])
{
	if(strcmp(cmd,"/at",true)==0)
	{
	new cmd[128], tmp[512], idx;
	strtok(cmdtext, idx);
	IsPlayerAdminLevel(playerid, 2);
		{
	new sendername[128];
	new string[128];
 	tmp = strtok(cmdtext, idx);
			GetPlayerName(playerid, sendername, sizeof(sendername));
			new length = strlen(cmdtext);
			while ((idx < length) && (cmdtext[idx] <= ' '))
			{
				idx++;
			}
			new offset = idx;
			new result[64];
			while ((idx < length) && ((idx - offset) < (sizeof(result) - 1)))
			{
				result[idx - offset] = cmdtext[idx];
				idx++;
			}
			result[idx - offset] = EOS;
			if(!strlen(result))
			{
				SendClientMessage(playerid, 0xFF0000FF, "USAGE: /at message");
				return 1;
			}
			format(string, sizeof(string), "[ ! ] %s", result);
			SendClientMessageToAll(0xFF0000FF,string);
		}
		return 1;
	}
return 0;
}

EDIT: I read the pawno compiler and fixed a few things, if they are wrong, feel free to correct me.
