in reply to Adding scalars but with a twist..

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.
