For some reason I couldn't see where the scalars and arrays were in this.

Here's a tool you already have to help you with this: Perl debugger!

Use the x command to see what a variable holds. It shows you the complete structure as if it were an array at the top level. (So hashes show up better if you escape the percent sign, as in the first example below).

c:\perl\perl>perl -de 0

Enter h or `h h' for help, or `perldoc perldebug' for more help.

main::(-e:1):   0
  DB<1> %x = ( 123, [ qw(one two three) ], 456, [ qw(four five six) ],
+ 789, [ qw(seven eight nine) ] )

  DB<2> x \%x
0  HASH(0x1d6c490)
   123 => ARRAY(0x15d52a4)
      0  'one'
      1  'two'
      2  'three'
   456 => ARRAY(0x1d6c628)
      0  'four'
      1  'five'
      2  'six'
   789 => ARRAY(0x1d6c664)
      0  'seven'
      1  'eight'
      2  'nine'
  DB<3> @x = ( { 1, "one", 2, "two", 3, "three" }, { 4, "four", 5, "fi
+ve", 6, "six" }, { 7, "seven", 8, "eight", 9, "nine" } )

  DB<4> x @x
0  HASH(0x1d70b24)
   1 => 'one'
   2 => 'two'
   3 => 'three'
1  HASH(0x1d97a78)
   4 => 'four'
   5 => 'five'
   6 => 'six'
2  HASH(0x1d97ab4)
   7 => 'seven'
   8 => 'eight'
   9 => 'nine'

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.
