Try this

pawn Код:

OnPlayerCommandText(playerid, cmdtext[])
{   
 if (strcmp("/cmds", cmdtext, true, 10) == 0)     
 {              
SendClientMessage(playerid, 0xFFFFFFFF, "SERVER: This is the /help command!");       
 return 1;   
 }   
 return 0;}

Edit: Using mobile, that's why I can't fix the loose destination error.
Edit1: Fixed a bracket.
