Hmm. It sounds like that may be the problem. I'll try just filling one line with water. I'll also get a screenie, maybe that will help.
*Edit* Sigh, I removed ALL the water from the entire level, and it still says maps can only have one water level! Okay, now for the screenies, I hope they'll help.

It's tiny, I know. And it's not complete, but it's the best my paint program would let me do. You'll notice there's no water, (as mentioned above) which is why the error message is making me so irritated.
*second Edit* Strange, it wouldn't let me post it. Oh well, just go the the link, hopefully it'll show up there.
