As RMGir already mentioned, you ought to enable warnings and use strict, this will probably save you some time chasing silly mistakes.
One problem I noticed is that you're passing a reference to $testfile_e as the -textvariable parameter, then assigning the reference to the Tk::Entry widget returned by the constructor to the same variable. This is not good. The -textvariable parameter should be a reference to a variable that is to contain the content of the Tk::Entry, only. I noticed in your screenshot that the filename Entry shows the widget path (.notebook.viewlog.frame.frame1.entry).
# line 134
$testfile_e = $incol2fr->Entry(
-text =>'No file selected',
-state => 'normal',
-textvariable => \$testfile_e,
-width => 60,
)->pack(
-side => 'top',
-anchor => 'nw',
-pady => 3,
);
Try changing the code to something like this:
# line 134
my $testfile_var;
my $testfile_e = $incol2fr->Entry(
-text =>'No file selected',
-state => 'normal',
-textvariable => \$testfile_var,
-width => 60,
)->pack(
-side => 'top',
-anchor => 'nw',
-pady => 3,
);
That's all I have time for at the moment, I hope that helps.

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).
