Try changing this:

#if "heatmap" in $report_options.split(",")


#if "heatmap" in str($report_options).split(",")

Although $report_options acts a bit like a Python string, it isn't one,
and lacks lots of useful string methods. We can turn it into a string
using the Python str function.

I believe only within the <command>...</command> tag.
