Hi ,
The $ref in the sub foo where you get it and
I guess , from the way you populate your hash in the sub bar , you should be getting the location by having
sub foo {
my $location_text = $locations('id');
}
The passing of hash can be through a reference too like
sub bar {
return \%locations;
}
sub foo {
$locations = &bar($dbh);
print "The reference returned from bar is : [$locations]
+\n";
%location_Names = %$locations;
}
You can use some debugging to see the hash values in course of program like use Data::Dumper which will give you the hash's values in course of your program in tree forms itself , so that it shall be easy and helpful

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
