compiles without problems.\sp
-- or, for that matter,\sb
-- unless you want to come to grief. (Hint:\sp
and\sp
are short for superscript and subscript.)\def
(which is not LaTeX) - using\newcommand
would have triggered a redefinition error. It's a good habit to use it especially for short macro names, where clashes are more probable.\newcommand
not\def
---to see if this appears anywhere. This method doesn't find the culprit every time, and it certainly doesn't give the full answer given below, but it can help diagnose the issue. [*I feel that it's a good tip; it works well for me, at least!]
