What is going on is that your syntax is illegal.
You want
predict predictions, xb
Look again at the help. -predict- takes one new variable name (hence the
error message); also -xb- is an option to be specified after a comma.

Not really sure what's going on. Have checked past messages, and only
one
other reference to this error message, which I am not sure is related to
this.
What I am doing:
xtreg on 11 independent variables, with 11 fixed effects
predict xb predictions
At the predict command, I get the beautiful red error message "too many
variables specified". I have used xtreg and then predict many times,
with
much larger regressions, and never had a problem.
