After quite a bit of searching, I finally found a macro that will allow you to link two trade skills at once.
Since I receive hits on my blog almost every day concerning this very thing, I figured it would probably be a good idea to share it with you. So here you have it, a macro that will post both of your Professions into chat with a single click, and from a single macro.
/script SendChatMessage(select(2,GetSpellLink(“Tailoring“))..select(2,GetSpellLink(“Enchanting“)),”CHANNEL”,nil,GetChannelName(“Trade – City”));
Just change the two professions I have underlined up there to whatever your own professions happen to be, and away you go.
UPDATE: When you copy this macro you also need to replace the quotation marks as well as the dash in “Trade – City”. I assume that the problem is caused by the font used in the blog, but I cannot say for sure. Just delete the quotes and dash and then type them back in and it will work.

Interesting. Do you have the professions that you’re trying to link?
I have never seen those error messages before. Let me do a little looking around and I will get back to you.

Psynister I’m getting the above LUA errors as well. I read your blog and the how too, and now I’m getting those errors.
../script CastSpellByName(”Jewelcrafting“);SendChatMessage(”LFW “..GetTradeSkillListLink(),”CHANNEL”,nil,GetChannelName(”Trade – City”));CloseTradeSkill();
is coming up with the same error as the poster above me showed you.

/script SendChatMessage(select(2,GetSpellLink(“Tailoring”))..select(2,GetSpellLink(“Enchanting”)),”CHANNEL”,nil,GetChannelName(“Trade – City”));
/script SendChatMessage(select(2,GetSpellLink(”Tailoring“))..select(2,GetSpellLink(”Enchanting“)),”CHANNEL”,nil,GetChannelName(”Trade – City”));
Alright, take a look at the two examples I have here. The first line is the one that I copied straight out of the game. The second is the one that I copied out of my text up above.
What I found here is that the double-quotes and the dash between “Trade – City” are what causes the error. Technically, it’s the quotes that cause the error and the dash simply causes it not to work at all. I’m not sure if it’s the font that’s the problem, or what, but if you copy the macro and then replace all of the quotes and the dash then this will work.

If you look at the second quotes mark at the end of Tailoring and Enchanting, you’ll see it’s the same as the first quotes mark — This is probably what’s causing the error. As for the dash, when typing in Word and other text editors, you can type a double hyphen “–” and the editor will autocorrect it to an en dash “–” which the game may not have coding to do this auto correction (as the two are separate ASCII codes).
yes, I am a HUGE nerd.
Great script tho! Will definitely use it. :)
