Syntax error in ruby script (unexpected keyword_end and unexpected $end)

I am writing some code as a solution for a programming problem. I have just introduced a new function into my solution which is causing the following errors. Note that the errors are not there without this function.

search.rb:48: syntax error, unexpected keyword_end
search.rb:68: syntax error, unexpected $end, expecting keyword_end

I realize that this is caused by a mispaced end. I just can't find it. (I have marked the location of the first error with a comment. The second error is the last line of code and not shown here.)

def processing_function
    qcount = pcount = $n
    qstrength = 0
    $query_hash.each do |qkey, qvalue|
        print "Q",qkey,": "
        $page_hash.each do |pkey, pvalue|
            qvalue.each_index do |i|
                pvalue.each_index do |j|
                    if qvalue[i]==pvalue[j]
                        qstrength = qstrength + qcount*pcount
                    end
                    pcount--
                end #** This is line 48. First error occurs here. **#
                qcount--
                pcount=$n
            end
            if qstrength!=0
                print "P",pkey," "
            end
            qstrength=0
        end
        print "\n"
    end
end

Ruby doesn't have -- or ++ operator. Use, for example += 1 instead.

There is short article about differences for C/C++ and Ruby.
