I recently started learning the Portal 2 Authoring toold and already have done my first map, but it has stopped working. First I've done the chamber and put there items. I loaded it and it worked. Then I closed, added the toxic liquid and map broke. When I delete something, that indicates the console it show me other errors.(It's a trigger or a prop)
What do I do? I can show you the map, if you'll want.

Sorry, if my English is unclear. =D

The way to solve a leak is to go to the bar at the top of Hammer, click "Map", then look down the list until you find "Load Pointfile". It will ask if you want to load the default one, click yes. A red line will now appear in your map. Follow it until you find the gap in your geometry. If it is running through geometry, make sure that brush isn't tied to an entity (func_detail is the most common).

Chances are, you don't have a floor under your toxic goo.

Hopefully that addresses your problem.

I have next ask: How can i post my map in the Steam Workshop, which use the custom content (textures, sounds and e.t.c)?

Sorry, if the answer has already been somewhere on the forum. I couldn't find it.

And if you have your own sounds/textures in there you'll need to pack them in the bsp with Pakrat or a similar program (you should be able to find it through Google if you don't already have it).

In order to make the vote window appear when ppl finish your map, you should also fire the following output via a trigger_once for example placed along the departure elevator ride:

- OnTrigger > @relay_pti_level_end > Trigger
