G'day g_speran,
As ++swl hinted, you may be commenting out the argument.
Arguments with no hashes:
$ perl -E 'say "Args (@ARGV): ", 0+@ARGV' A B C
Args (A B C): 3
Arguments commented out with hash:
$ perl -E 'say "Args (@ARGV): ", 0+@ARGV' #A B C
Args (): 0
Arguments with an escaped hash to prevent commenting:
$ perl -E 'say "Args (@ARGV): ", 0+@ARGV' \#A B C
Args (#A B C): 3

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.
