    <p>I'm loading data from a .txt for the purposes of scraping. However, the URL requires that I break that variable up and do +/- 2 to it. For example, if the value is 2342, I need to create 2340 and 2344 for the purposes of the URL. </p> <p>I took a guess at how to break it up:</p> <pre><code> $args{birth_year} = ($args{birth_year} - 2) . '-' . ($args{birth_year} + 2); </code></pre> <p>How do I then put it in the URL?</p> <p>Here's the relevant part of the code:</p> <pre><code> use strict; use warnings; use WWW::Mechanize::Firefox; use Data::Dumper; use LWP::UserAgent; use JSON; use CGI qw/escape/; use HTML::DOM; open(my $l, 'locations2.txt') or die "Can't open locations: $!"; while (my $line = &lt;$l&gt;) { chomp $line; my %args; @args{qw/givenname surname birth_place birth_year gender race/} = split /,/, $line; $args{birth_year} = ($args{birth_year} - 2) . '-' . ($args{birth_year} + 2); my $mech = WWW::Mechanize::Firefox-&gt;new(create =&gt; 1, activate =&gt; 1); $mech-&gt;get("https://familysearch.org/search/collection/index#count=20&amp;query=%2Bgivenname%3A$args{givenname}20%2Bsurname%3A$args{surname}20%2Bbirth_place%3A$args{birth_place}%20%2Bbirth_year%3A1910-1914~%20%2Bgender%3A$args{gender}20%2Brace%3A$args{race}&amp;collection_id=2000219"); </code></pre> <h3>For Example</h3> <p><em>Input is:</em></p> <pre><code>Benjamin,Schuvlein,Germany,1912,M,White </code></pre> <p><em>Desired URL is:</em></p> <p><a href="https://familysearch.org/search/collection/index#count=20&amp;query=%2Bgivenname%3ABenjamin%20%2Bsurname%3ASchuvlein%20%2Bbirth_place%3AGermany%20%2Bbirth_year%3A1910-1914~%20%2Bgender%3AM%20%2Brace%3AWhite&amp;collection_id=2000219" rel="nofollow">https://familysearch.org/search/collection/index#count=20&amp;query=%2Bgivenname%3ABenjamin%20%2Bsurname%3ASchuvlein%20%2Bbirth_place%3AGermany%20%2Bbirth_year%3A1910-1914~%20%2Bgender%3AM%20%2Brace%3AWhite&amp;collection_id=2000219</a></p>

    3. COIs there something more to this than creating the URL with sprintf where you put have ...%d-%d... and use $args{birth_year} - 2 for the first placeholder and $args{birth_year} + 2 in the second?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
