Autotext filename and path

[Heidi]

When I try and insert the filename and path under the
header/footer tool bar it does not exist. Filename
exists, but not Filename and Path. It did at one time,
but I did something to screw up the definition of this
and now it is not there under "Autotext." After an
unistall and reinstall, "Filename and path" are still not
an option on the Header/Footer toolbar. However, when I
go to "Autotext" and choose Filename and path, it will
insert the following: "{Filename\p]. How do I get the
actual path and filename back like it was before.

Any help would be wonderful
