Adding scores

Users

Hi All,

I need to add scores assigned to item values, and some caculated in data
nodes.

I've used the following syntax.

sum(/data/start_commcare, /data/opening_commcare, /data/logging_in,
/data/navigation_in_form, /data/navigation_between_forms,
/data/choosing_form, /data/finding_client, /data/case_details,
/data/use_all_forms, /data/ask_client, /data/skip_questions,
/data/counsel_on_all_topics, /data/record_accurately, /data/Entering_text,
/data/enter_dates, /data/entering_numbers)

When I test in Cloudcare I get the following error:
internal error handling request: <type
'org.javarosa.xpath.XPathUnhandledException'>:
org.javarosa.xpath.XPathUnhandledException: XPath evaluation: cannot handle
function 'sum'

How can i resolve the problem?

Thanks,
Sangya

sum() can only be used on nodesets. just use + to add everything together.
