Custom Units

I have never made custom units before, other than just editing standard units. I have created two custom units today, and in the object editor thaey are under Custom-Human-Melee-Buildings. My problem is that when I go to use the two units in my map, they do not show up with the other human units. Is there another step I have to take to use them? Thanks,

There is a list close to the human that reads "melee", you can change it to "custom" and use your units

Thanks, lol it was something easy right in front of me. Thats how it always is. I got it now. Thanks again,
