Problem with Eqn template
"I've added a proof sequence using the eqn template, and despite my best efforts the parser barfs on it. It makes a horrendous mess that I can't work out how to clear up."
- What's probably happened is that you have included instances of
|in your $\LaTeX$.
- The MediaWiki template parser takes precedence over the MathJax one, and views
}}as the beginning and end of the invocation of eqn, thus breaking the $\LaTeX$ in two. Similarly, it interprets
|as the MediaWiki instruction to interpret what follows as a parameter value.
