Running total with Layout Editor with BI Publisher 11g

Question

Hello,
I'm trying to create a report with BI Publisher Layout Editor using the "running total" option. My XML looks like this:
<G_1>
<REGION>MZ</REGION>
<G_2>
<INVOICE_NB>1</INVOICE_NB>
<VALUE>1000</VALUE>
</G_2>
<G_2>
<INVOICE_NB>2</INVOICE_NB>
<VALUE>3000</VALUE>
</G_2>
</G_1>
and I want to insert in the layout a data table with this information:
|REGION | RUNNING TOTAL
|MZ | 1000
| | 4000
I inserted a new data table with the region and the value. I grouped the Region to the left (Grouping -> Group Left).
Then I selected the Value column and clicked on Formula -> Running Total, but nothing happened with this last step. Am i forgotting something? How can I display Running Totals on a Data Table with BI Publisher (using Layout editor and not RTF Templates)?
Thank you,
Josep

Use the following: Declare a variable before the loop: <?xdoxslt:set_variable($_XDOCTX, 'RTotVar', 0)?>
In your loop: Include the following code for your Running Total Column: <?xdoxslt:set_variable($_XDOCTX, 'RTotVar', xdoxslt:get_variable($_XDOCTX, 'RTotVar') + VALUE)?><?xdoxslt:get_variable($_XDOCTX, 'RTotVar')?>
For an example of the RTF : Look for the files under your local BI Publisher Desktop installation: BI Publisher Desktop\samples\RTF templates\Advanced\Running Total
