Because this is a simplification that demonstrates the problem nicely ;-)

<dtml-var "('<TD BGCOLOR=%s>&nbsp;&nbsp;</TD>' %
bgcolor(???))*(nav_indent_level-1)">

...is the real thing, where bg color is the Python Script.

The workaround I have is:
<dtml-let bgcolor=bgcolor>
<dtml-var "('<TD BGCOLOR=%s>&nbsp;&nbsp;</TD>' % bgcolor)*(nav_indent_level-1)">
</dtml-let>

...which is kinda sucky :-S

How should I be calling a python script from a python expression in DTML and
passing the namesapce in the process?

cheers,
