Report filtering per company

I have a create report function showing reports for every record that
is listed in the tblCalls table.

In my situation one report per call that comes from a company.

I would like to have a company pre-selected before the forms are
created and it then shows only the reports from the selected company.

The data in the reports comes from the table Calls that has various
fields. These fields are filled with the frmCalls form

Company names are listed in tblCompany


Anybody can help me?
