dtml-in provides some variables that may be enough. If not move it to a
Python script, do the work there and do simple presentation from dtml. From
the online help:

Summary Variables
    These variable summarize information about numeric item variables. To
use these variable you must loop over objects (like database query results)
that have numeric variables.

total-variable
    The total of all occurrences of an item variable.
count-variable
    The number of occurrences of an item variable.

etc...

Hi *,

I have a dtml-in which lists both quantity and cost of items in my table.

I am generating the total for each item row like so -

<dtml-var expr="cost * qty" fmt="dollars-and-cents-with-commas">

What would be the practical approach to calculating the sum of all totals
for each item here?

Regards,
Michael Fox
