Dear List, 

i hope somone can help me. 

This litte example is from the wiki, i wanted to try \placeformula 

\placeformula[formula:aformula]

\startformula

y=x^2

\stopformula

\placeformula

\startformula

\int_0^1 x^2 dx

\stopformula

Command Line:   context.exe --synctex=-1 "mathtry.tex"

Somewhere in the math formula just ended, you used the stated character from an

undefined font family. For example, plain TeX doesn't allow \it or \sl in

subscripts. Proceed, and I'll try to forget that I needed that character.
