Scientific Word/Workplace ⇒ Undefined Control Sequence when citing a Reference

[michaelwujian]

I use bibliography in this editor. When I compile, I get the error message:

Code: Select all

LaTeX Font Warning: Font shape `T1/cmss/m/it' in size <7.6> not available
(Font)              Font shape `T1/cmss/m/sl' tried instead on input line 211.

? 

However, in the bibtex window, it shows success.

cd d:/swp55/temp/
d:\swp55\TCITeX\web2c\BibTeX.exe d:/swp55/temp/swp0001

Code: Select all

This is BibTeX, Version 0.99c (Web2C 7.5.6)
The top-level auxiliary file: d:/swp55/temp/swp0001.aux
The style file: achicago.bst
Database file #1: kam104.bib
[BibTeX finished]

I find in the bbl file the content is:

Code: Select all

\begin{thebibliography}{}

\bibitem[\UnexpandableProtect\SCcite{Coppola}{Coppola}{2008}]{Coppola08}
Coppola, A.
\newblock 2008.
\newblock \Wrapquotes{Forecasting oil price movements: Exploiting the
  information in the futures market}.
\newblock \textitswitch{Journal of Futures Markets}  28 (1): 34--56.
\newblock Coppola, Andrea.

\end{thebibliography}

And the reference in my .bib file is:

Code: Select all

@article{Coppola08,
   author = {Coppola, A.},
   title = {Forecasting oil price movements: Exploiting the information in the 
futures market},
   journal = {Journal of Futures Markets},
   volume = {28},
   number = {1},
   pages = {34-56},
   note = {Coppola, Andrea},
   year = {2008}
}

I couldn't find the reason. Can any one tell me?

Please post a minimal example that demonstrates the problem.
