Ruby: else without rescue is useless

It looks like the else block is not part of an if statement. Am I correct in assuming you want it to provide an alternative path when if @@counter > 0 is false? If so, get rid of the end that's on the line above the else, e.g.:

if @@Counter > 0
    # ... processing ...
else
    # ... alternative processing ...
end

if condition
  # …
else
  # …
end

not

if condition
  # …
end
else
  # …
end
