Crosstab creation in a group

Hello,

I'm new in XML Publisher and I'm trying to create a crosstab in a rtf mode

That crosstab contians results  of companies  by period, devise and type of transactions.

The crosstab has to show data for each company.

So , I'm trying to make the crosstab embedded in a group / Company group.

My XML data is done according that for a group G_Company  I have some groups of G_Period.

However, in the results, for each company  I have a table that gives the total amount for all the companies.

What am I doing wrong?

Thanks!
