Please I wish to achieve a replica of exactly the result obtained with this code below except that I want the chapter one heading Instead of 1. when I used the following code `
\usepackage{fmtcount}
\renewcommand{\thechapter}{\Numberstring{chapter}}
it worked, but it disfigured my table of contents and I started seeing some numbering like one.1, three. 4 and so on. Is there any way I can maintain my figure numbering in the table of contents whilst also changing the chapter headings in the body of the document to text? Any assistance will be appreciated
