could somebody tell me why I get an error by using the second equation in the added lyx-file?
This is the relevant part of the lyx-file: \layout Standard If I take the second equation out, dvi gives no error. \layout Standard \begin_inset Formula R=Rh/2+(ZZ-4) \end_inset \layout Standard but with this one it gives errors \layout Standard \begin_inset Formula R=Rh/2+(ZZ-4)+K_{ab} \end_inset I am using Lyx Version 1.3.2 Mai 2003 and Mandrake 9.2 buffled: Wolfgang
