You have to use eval="true" for <m> if you have variables inside. And
make sure the display is using MathJax.
Try this:
<m eval="on" display="mathjax">$$ \frac{$numer}{$denom} \left[ \pi +
\sum_{n=1}^{\infty} \frac{$sum_numer}{$sum_denom_n_coeff n -
$sum_denom_const} \cdot \sin($w nt) \right] $$</m>
If you put the whole expression into a variable, you will also have to
escape the "\" with "\\".

Hi Damien,
Thanks for your reply. At least now I know that I was chasing the wind. I was able to get close by
using Sigma in place of sum in the expression, but then only the "n" was subscripted, not
the "=1" part, even though I used braces: _{n=1}...
I had initially tried to render the equation in the xml portion of the problem, but when I
did that I had a lot of trouble properly displaying some of the variables using the
<m>$...$</m> command. It worked in some places but not others.
This is as close as I have been able to get to a proper expression:

In the xml portion I have been able to render it nicely:
[cid:image002.png@01D26DF6.82F21010]
...but only if I hard-code the constants in the two fractions and inside the
sine. Is there a way to display variable values from the perl script in place
of the constants? I have tried a few things, but all were unsuccessful.
Thanks,
