I found a tutorial which may help you (you probably need to start about half way down, since you've made the basic MATs already). You should delete all the unaltered materials altogether first of all. Then tt says "double click on each [of the other settings] to disable it" - in your case, turn off everything other than the transparency map section. Hope that helps.
