Hi Héctor!
    
    I have the contacts.rec file below:
    
    Name: Granny
    Phone: +12 23456677
    
    Name: Doctor
    Phone: +12 58999222
    
    Name: Dad
    Phone: +12 88229900
    
    And I want to display the Name in the last record using the script
    script_variable_index.sh below:
    
    number_of_records=$(recsel -P "Count(Name)" contacts.rec)
    name_in_last_record=$(recsel -P Name -n "$number_of_records" contacts.rec)
    echo "Name in last record: $name_in_last_record"
    
    But I get the following output:
    
    Name in last record:
    
    So, not displaying any Name.

That's because the aggregate Count(Name) is returning 3 (there are 3
instances of the field Name), whereas -n expects a 0-based index.
