Unreal Modding

Not sure if anybody here is familiar with the Unreal Ed but I'd figure to ask anyway.
I'm trying to create a field area from the dotHACK series.
I've made my grayscale heightmap but having problems with the terrain appearing. I'm following the tutorial from unreal wikicreating a terrain.
How do I get my terrain to appear, it's just not showing up. I've rebuilt all, I've checked my strength, I've even saved, exit, and reopen. Any ideas on what I'm doing wrong?
Also I've even created a heightmap in max and exported as a dxf file. How do import it into Ued?
Thanks in advance.

Don't know about the second question, but is the terrain not appearing within just the program, or also when tested?

I realized my mistake...pretty simple mistake actually.
I forgot to set the bterrainzone=true.
