Petros,

- Open the report.
- double-click on the Title band
- add expression TOC("Init")) into On Entry: field
- double-click on the Group Header
- add expression TOC("From", _PAGENO, category) into On Entry: field
- double-click on the Group Footer
- add expression TOC("To", _PAGENO) into On Exit: field

That's it. This will generate a cursor with the table of contents when you run or preview your report.
