Hello guys, i used this theard: 

all works fine, but i have 2 problems:

1) When i change channel, its works, but under minimap is still CH1 (when im on ch2 for example)

2) The information: "You're already in the selected channel!" works only on CH1, for example, im on CH1, trying to change channel to CH1, information works, but when im on CH2 and trying change to CH1 there is that information and i cant change channel.

I know its hard to understand me, but i hope u will help me, sorry for bad english guys
