[Gmail-Users] What am I doing wrong

I'll try again.
Hello to Group members,
I am a new gmail person and would like to know how to make the auto
fill work when when I fill in my email address and password to log into
my mail? some one answer. At least let me know if anyone is seeing
this message.

There is one more thing what is digest email or abridged email, which
ones do I have to choose?
