SendChatMessage issues when detecting channelNumber

[Cidwel]

Hi all! I have a trouble. What is the best way to get the channel number using only it's channel name? I mean, if, i wanna spam in General but I don't want to supose that General number channel is 1.

I think that it would be something like this:
SendChatMessage("lol","CHANNEL",nil,GetChannelName("Trade"))

but this only works for me in some locations like Acherus. So strange... Could be it nerfed?

Thanks!

You should always make sure you have the right channel name.

In this case, it's actually "Trade - City".

I'm Completely new to Lua and WoW interface customization but on my travels i have come across the GetChannelName() function. Maybe that helps?
