I'm working on a pattern that calls for crossing bar. What do crossing bar mean? Here is the pattern http://www.knitting-crochet.com/knidoustadoi.html
I took a look at the pattern via the link you provided, and the 'cross bar' only appears in Row 8. It isn't a stitch, but informational - it is telling you that the cross bar mofif (whatever that is) begins here. Just follow the other stitches around the phrase, and ignore it for now.
