One possible reason for this problem is that you've defined them using my, but you've defined them in the wrong place.
For instance, if you've done
if($foo){
my $bar = 'baz';
}
print $bar;
Then you'll get the warning that $bar is undefined, because it only exists inside the "if" block.
In other words, just adding my anywhere you declare a variable isn't going to solve your strict problems. You have to know what it means for those variables.

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).
