PDF with a single filter

[malfaro_2000]

Hello community, I have an ENTRADAS table like the following image:

I need to obtain a PDF report with the selection of a single CATEGORIA as I try with the following form:

This form is associated with the INFORME CATEGORIAS table:

With a virtual column called REPORTCATEGORIAS, whose syntax is the following:

Resulting in what the image of the REPORTE CATEGORIAS form shows.

But I don't know how to program it in the template, so that the results of the selection are seen as seen in the form, with all the data.

Please help me create the template that allows me to obtain the report in PDF as shown in the image of the form.
As an example, I attach an image of how I intend to make the template, it is just an example.

Thank you
