Hi Richard,

I'd be willing to bet that the problems stems from your using the "%" in the
menus. Special characters sometimes create problems.  Like I was trying to use
FB^3 in a menu and the carat had to be handled specially.  Try spelling it out
instead, "2 percent".  I also suspect you may have two - unrelated problems,
though I could be wrong.

Don't bother to change all of them.  Just change one and test for it.

HTH,

Joe Wilkins
