Update: This is solved. The note that 'Runtime warnings triggered in elsif conditions are reported with the line number of the original if condition.' was the key. Below is the change to the 'elsif' statement I made (making it the trinary operator). Thank you again to everybody who responded!

elsif (($cur[2]) > ($sec[2] ? $sec[2] : 0)) { ----------------------------------------------

Hi, I have the following code snipped that generates warnings in places that I cannot find a rhyme or reason for: 
135                # new record is the highest
136            print "Begin: i=[$i], cur[2]=[",$cur[2],"], win[2]=[", 
+$win[2], "]", "\n";
137            if ($cur[2] > $win[2]) {
138                $top2{$key1}{$key2} = [$votes_office_ttl,@cur,@win]
+;
139            }
140            elsif (0+$cur[2] > 0+$sec[2]) {
141                $top2{$key1}{$key2} = [$votes_office_ttl,@win,@cur]
+;
142            };
143            print "End: i=[$i], cur[2]=[",$cur[2],"], win[2]=[", $w
+in[2], "]", "\n";

And I get the following warning emitted interleaved with my print statements: 
Begin: i=[32], cur[2]=[20], win[2]=[100]
Argument "" isn't numeric in addition (+) at ./x.pl line 137, <$fhin> 
+line 32.
End: i=[32], cur[2]=[20], win[2]=[100]

I don't understand why the boolean statement at 137 is being emitted... you can see the values of the variables going into the boolean comparison beforehand. In addition, the 'i' variable is the line number of the source file for the values coming in, and line 32 is the first line that triggers this error. Any ideas?
