Can you pls explain it a bit more in detail - afraid I'm still a bit new to Zope and dtml/python. What would the Script (Python) look like? Thanks for your help! :-)

This is a pure programming exercise. You said:
VALUE SEQNUMBER 13 1 10 2 11 3 10 4 12 5 ...
I want to accumulate my values so the result will be:
VALUE SEQNUMBER ACCU 13 1 56 10 2 43 11 3 33 10 4 22 12 5 12
So apparently you need to accumulate the *remaining* values. The script would receive a list of values: [13,10,11,10,12] and return a list of tuples [(13,56),(10,43),(11,33)...] A pure python function would look like this: def accumulate_remaining(values): values = map(float, values) # make sure they are true numbers result = [] for i in range(len(values)): result.append((values[i], sum(values[i:]))) return result To convert it to a "Script (Python)": create the script, name it as the function, leave out the "def" line and put the body inside the script, declare a single parameter "values". Then use <dtml-in "accumulate_remaining(your_list_of_values)"> and inside it, <dtml-var "sequence-item[0]"> <dtml-var "sequence-item[1]"> or something like that. This has not been tested but should work. The dtml syntax may be wrong, tough, I dont use dtml anymore. Gabriel Genellina Softlab SRL __________________________________________________ Pregunt�.
