How to load custom maps?

[illuknisaa]

I made this simple map (1 room and player spawn) with doombuilder.

I want to run it but how do I do it?

I can start the map via doombuilder itself but not with gzdoom (drag and drop onto gzdoom)
When I start gzdoom my map doesn't show up in the popup window.

I also want to run my map with brutal doom, how can this be done?

Does it matter what map format I use?

GZDoom is usually a case of drag and drop, that's worked fine for me and my my 300 or so WAd's. Not sure why it's not working for you.

What map number did you assign it to?

map01

I got it working using cmd parameters "-file" but dragging and dropping doesn't work.
