Multi-level PWADs

[blarg]

How do I create a new level using the same PWAD? When I choose "new map" and try to save my map under a PWAD with one level, DB asks me whether I want to overwrite or not. If I choose yes, MAP01 from my PWAD is overwritten.

Should I chose no, or am I doing this wrong?

Create a new map. Click on File, and then Save Map Into. Select the "parent" PWAD and then save it in there. Make sure if there is already a MAP01 in the parent PWAD that you don't try to save another MAP01 in there, or else the first one will be overwritten.
