and then i had create a file in this user ;;;;;
and when i try to save this file then it's give error
"create" E212 can't open this file for writing.
so what can i do now

Who knows?? Your question is very vague, and hard to follow.

- Where/how did you create the new group and user? With what parameters?
- How did you create the file "in this user"??
- What program were you using?

Chances are, the users home directory doesn't have the right permissions. Read the man pages for the chown and chmod commands. The home directory should be "chown <user id>:<group id> <home directory name". Same for the file.
