This means that the shell thinks x is an integer variable.  Check this

  print ${(t)x}


  typeset +i x

to revert it to a scalar.  On the command line, simply "unset x" would
be good enough.

Obviously, you'll have to check what you've been doing to see why
it would have become an integer.  It certainly wouldn't do that because
of a "for" loop.  If you've still got the old command list associated
with x we can probably work it out.
