I put there my whole code. Trying to determine location address. My script should create still one marker with geocoded address (in console - variable kktina).
But, unfortunately, there isn't everything OK. Because by script still resolves previous location (or it takes previous coordinates, dunno). Maybe there is an error in code, but I'm not able to do this anymore..
So asking for help, thank you!

You can't do this:
the Geocoder is asynchronous, the value of address is undefined when it is returned.
Use the returned data inside the callback function instead, something like this (not tested):
