Programing Macros for Trade Channel

I took a year off of WoW, back going on month 3. Hitting a problem, so I am hoping someone can help me out here.

In the past I was able to link my profession into a macro as I wrote it. Run it, hey everyone enjoys a good commercial on Trade, and I make money! Or at least get good PR.

It seems since one patch or another I can’t link my profession like I used to, I am hoping someone can help me out here.
