I am trying to add in Odoo ORM page but target page it was not able to display.

Hilar, 

Thank you for your interest in helping me out.

The view is backend...  MathJax, after the page loads, looks for latex expressions between "$" signs (for example: $\sigma$) and converts to the graphic symbol of the greek letter in svg.  I was able to make it work with the following code (see below).  It works but only once.  As soon as I load a new view, mathjax does no longer work.  The following line is supposed to re-execute MathJax everytime the page is reloaded.  MathJax.Hub.Queue(["Typeset",MathJax.Hub]);  but it does not work for some reason.

Thanks again,

Fernando
