nested block

I have the following receipe. The idea is:

1. Filter messages that have a ratio of quoted-unquoted lines more than 1:2
2. put all filtered messages in 2in1 folder
3. write down the time, sender, subject, and size in a log file
4. For all other messages that pass the filter, write the same info as in
   (3) in a separate log file
5. Except for messages from me, leave the messages in (4) in the default 
   incoming folder

My procmail log file give some errors:

  Total  Number Folder
  -----  ------ ------
      0       1  ## procmail: Closing brace unexpected
      0       1  ## procmail: Error while writing to ""
      0       2  ## procmail: Skipped "{"

Can anybody help?
