Hmm... That looks confusing but ill give it a go. The link you provided is dead, too.

Edit: [s]I tried out that macro. I replaced Fish Oil to the item that I wanted, but all it does is act like I clicked the item - It puts it on the mouse but doesn't throw it into the trade. Any idea? I examined the macro a bit but I cant figure out what to change.

[/s]Edit: Never mind, Im dumb. MAJOR thanks!!
