Error which occurs while loading into the jmax init.el file for the first time:

This is copied from the message log:
Loading /home-research/jboes/Dropbox/jmax/jmax-org.el (source)...
find-file-noselect: Wrong type argument: stringp, nil

Error was avoided by commenting out the following lines in jmax-org.el:
;; I like a random bibtex entry in my agenda.
;(defun formatted-bibtex-entry ()

I took this code out of jmax. That should solve this problem.
