# Get chapter numbers as text in the report class

im trying to get my chapter numbers printed as text, but on the way there i messed up my section numbers with text "ONE" and "TWO" an such, here is what i was doing,

This code centers, pull up and changes font to normal size the chapter headings, I needed to change chapter numbering to text i.e. "CHAPTER 1" becomes "CHAPTER ONE". So far, I have the digit to text part figured out, but how to make the stuff uppercase and stop it from tripping over the error in the appendix that says `missing number treating as zero` i can not figure out.

``````\usepackage{titlesec}
\usepackage{fmtcount}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\renewcommand{\thechapter}{\NUMBERstring{chapter}}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\titleformat{\chapter}[display]
{\normalfont\normalsize\bfseries}
{\filcenter\chaptertitlename\ \thechapter}{10pt}{\filcenter\normalsize\MakeUppercase}
\titlespacing*{\chapter}{0pt}{-50pt}{40pt}  %%%%  pull up chapter heading
\titleformat{\section}{\normalfont\normalsize\bfseries} {\thesection}{1em}{}
\titleformat{\subsection}{\normalfont\normalsize\bfseries} {\thesubsection}{1em}{}
\titleformat{\subsubsection}{\normalfont\normalsize\bfseries} {\thesubsubsection}{1em}{}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
``````

how can i have uppercase "one" and such instead of chapter numbers in the chapter heading, without interfering with the table of contents and the section numbering? i got all this from this other question and other places

• Don't redefine `\thechapter`, but rather say `\NUMBERstring{chapter}` in `\titleformat`. – egreg Nov 13 '13 at 14:21

``````  {\filcenter\chaptertitlename\ \NUMBERstring{\thechapter}}{10pt}{\filcenter\normalsize\MakeUppercase}
