When you assign to hash like that, Perl is expecting to see an even-number-sized list of elements to put in the hash- key/ value pairs. If $diary_data[0] is a reference (it is) to the array where the key/value pairs are (this I don't know), then you'll want to use
@{$diary_data[0]};
This resolves the pointer/reference and "enters" the array into the hash as key/value pairs. Then your print statements will work fine. Also, be sure to use strict;, use warnings;, and use diagnostics; for better error-reporting, though I'm not sure if you've already throw those in.

Update: Ovid's node is probably right, now that I reread your statement "returns array of hashes".

Update2: AgentM wins! Fatality!

AgentM Systems nor Nasca Enterprises nor Bone::Easy nor Macperl is responsible for the comments made by AgentM. Remember, you can build any logical system with NOR.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
