OK, so you first assign a name, so probably a string to $plants->[$i]{common} :
$plants->[$i]{'common'} = $plants->[$i]{'common_name'};

And few lines later, you try to store something in a hash ref:

$plants->[$i]{'common'}->[$jctr]{'sizes'} = $sizes->[$j]{'plantsiz +e'}.$sizes->[$j]{'unit'}; # ~~~~~~~~~~~~~~~~~~~~~~~

The underlined thing is a string (comment mine). You can't use a string as a hash ref under strict.

BTW, is $jctr ever different to $j (and $kctr to $k )? If not, you can improve readability by dropping two variables.

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

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.
