I'm trying to make a general environment for delineating sections of math with indented bodies, (proofs, definitions, etc).
I found that using the 'adjustwidth' environment in the 'changepage' package was what I needed for the indentation.
To make the general environment I followed along to the answer from this link:
Is there a \renewtheorem equivalent of \renewcommand, using amsthm and not ntheorem?
The syntax I desire is the following:
\begin{env-name}{Header}{Counter}[Punctuation][Note][indentation-size] for numbered environments
\begin{env-name}{Header}[Punctuation][Note][indentation-size] for unnumbered environments
and would produce the following: (unnumbered)
{Header}[Punctuation] [Note] \n
[indent with indentation-size] body text...
I'm pretty new to latex2e (or whatever) language, but I checked the environment definition and couldn't see what could be wrong.
Below is my package file containing what I believe is minimum requirement to reproduce the error.
\RequirePackage{changepage}
\RequirePackage{amsthm}
\RequirePackage{amsmath}
\RequirePackage{amsfonts}
\RequirePackage{xargs}

Below is the actual .tex file I'm using to compile the document.
% Testing document for proof formatting
\documentclass{article}
\usepackage{dummy_test}
\begin{document}
\begin{remark_unnumbered}{Claim}[.][Hello][2ex]
hello
\end{remark_unnumbered}
\end{document}
I'm not sure if this would be useful but I am using TeXMaker with MikTex to compile. Below are the two error printouts that I am receiving:
! Missing number, treated as zero.
<to be read again>
\relax
l.8 ...in{remark_unnumbered}{Claim}[.][Hello][2ex]
A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)
! Illegal unit of measure (pt inserted).
<to be read again>
\relax
l.8 ...in{remark_unnumbered}{Claim}[.][Hello][2ex]
Dimensions can be in units of em, ex, in, pt, pc,
cm, mm, dd, cc, nd, nc, bp, or sp; but yours is a new one!
I'll assume that you meant to say pt, for printer's points.
To recover gracefully from this error, it's best to
delete the erroneous units; e.g., type `2' to delete
two letters. (See Chapter 27 of The TeXbook.)
POST SOLUTION REMARK:
The marked solution fixed the errors and I found that in order to have the body text to be on the next line \hfill was added after \begin{tremark_unnumbered}[#3]. Thank you for your help.
