This is so simple which represents a time translocation of t1. I want Mathematica to compute v[0] and it is supposed to give t1 (ie. t sub 1). I typed in v[0] but Mathematica gives me 01 (i.e., 0 sub 1). Obviously it is not the correct answer. Can anyone give me some insight of this delima? Thanks a lot. Since my posting didn't appear to appear I post again Instead of using the notation packet I prefer to use fixed strings. Typo looks the same v[t_]:=t+Subscript["t",1] v[3] Cell[BoxData[ RowBox[{"3", "+", SubscriptBox["\<\"t\"\>", "1"]}]], "Output", CellLabel->"Out[5]="] The string "t" cannot be confused with the pattern name in t_. -- Roland Franzius
