If they are package variables, you can use symbolic references:
my $sum = 0;
foreach my $i (1 .. 80) {
no strict 'refs';
$sum += ${"Sel${i}Ttl"};
}
If not, you can use 'eval':
my $sum = 0;
foreach my $i (1 .. 80) {
$sum += do {eval "$Sel${i}Ttl"}
}
Or if you want to get fancy:
my $sum = 0;
local $" = "+";
eval "\$sum = @{[map {qq {\$Sel${_}Ttl}} 1 .. 80]}";
All code untested.

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).

or How to display code and escape characters
are good places to start.
