A field with a name that has characters it it other than alphanumerics,
hyphens, underscores, and periods?

Try fixing the field name not to have any such characters (for example,
don't put any spaces into it - if you want to separate words, use an
underscore; fields with spaces in the name don't work well in filter
expressions).
