Selfmade B3 command not working

[EvoloZz]

I have tried to write a b3 command for function I got in my mod but it doesnt seem to work... B3 doesnt turn on anymore after including my plugin with it.
Here's the command:

		    def cmd_flames(self, data, client, cmd=None):
        """\
        <player> - Give flames to a player
        """
        
        input = self._adminPlugin.parseUserCmd(data)
        if not input:
            client.message('^7Invalid parameters, you must supply a player name')
            return False
            
        else:
            sclient = self._adminPlugin.findClientPrompt(input[0], client)
            if sclient:
                self.console.setCvar('flames', '%s' % sclient.cid)
                return True 
	

The "flames" command works perfectly thru console, so the problem is in that command and i can't seem to find it... There might be just bad syntax somewhere but i never use python so i don't know the rules...
I just wrote that with my crappy experience with B3, so please help me
