$l.303 ...ph{Technician, View, Business_Plan, NULL} >$\rightarrow$\emph{Deny}... ? Process has been terminated ...  I am almost mad by this weird error!!! Could anybody help me?? ## migrated from stackoverflow.comOct 21 '13 at 21:40 This question came from our site for professional and enthusiast programmers. • the ">" is the problematic character. it should either be gone or also placed in the$$equation (you can't simply write > in text) – PascalVKooten Oct 18 '13 at 10:15 • Thanks for commenting. But after trying what you said(I just let the '>' go), the error still... – qingjinlyc Oct 18 '13 at 10:22 • Because, similarly, there are more of those < and > characters appearing in text. – PascalVKooten Oct 18 '13 at 10:24 • The underscores _ also have to be escaped (\_). It then works (in Business_Plan, that is). Welcome to the "wonderful" world of latex. – PascalVKooten Oct 18 '13 at 10:31 • Please read any introduction to LaTeX. – Martin Schröder Oct 18 '13 at 21:41 ## 1 Answer You can't simply use "<" and ">" in text, one option would be to use $<$ and $>\$.

Also, underscores can't appear in text, escape these: \_.
