I'm having some trouble with formatting of math equations, specifically fractions. The following is a code snippet that demonstrates the issue. 

[code snippet follows]
<!-- pt type="loncapa/perl">
$a = &random(1,5,1);
</scr -->

The fraction 1/3 is displayed as I would expect. On the other hand the fraction with the variable denominator bombs out in latex with an error message like:

**** Error: Fatal Abnormal eqdepth 2 on display equation exit, line 0
occured while attempting to convert this TeX:

I assume I need to somehow escape the $a to pass the value of the perl variable. Can anyone provide some guidance on this.

Thanks a bunch,
