Need help!
Hello.
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
Sounds like you've got a leak, which is when the map is not completely sealed from the "void", the infinite black space surrounding your map. Deleting the object that the log indicates will not solve it.
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. 
Oh, thanks! You're great! I could fix it!
Sorry for double-post.
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.
You need to use the p2map_publish application to upload non-PTI maps; it's default location is in C:Program Files (x86)Steamsteamappscommonportal 2bin.
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).
My maps: Double Bill / Jam / Oval Window / Gymnasium / Gymnasium Part 2 / Minimalism (collection) / Resolution
All feedback welcome!

Yeah, and also it's required that you include an instance into your map... wherever outside it; it's called "global_pti_ents", and you can find it into instances/p2editor/global_pti_ents.vmf. Without it, the p2map_publish.exe will say there's a problem with your map.
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

Make sure your map name is without spaces or the workshop will mess up your cubemaps if you have. Also, you can't pack custom particles, but, I don't think anyone uses them too much.
Thank you all.
