It would've been nice if you provided the admin system you're using, but still, the logic works this way:

• Player issues a command
• You check his level
• If it's 4 or bigger than 4, success
• If his level is less than 4 you display your error message

Код:

  
if(playerinfo[playerid][alevel] >= 4)  
{
    // Success.... 
}  
else if(playerinfo[playerid][alevel] < 4)
{
    // Something like "You can't use the command specified."
}
