[Click] Click for measurement

[sandeep]

Hi Guys,

I am using a simple example from "click for measurement" paper and facing
this error. Any ideas on how to correct it?

in0::InfiniteSource -> Queue
-> EtherEncap(0x0800, 11:22:33:44:55:66, 66:55:44:33:22:11)
-> Counter(COUNT_CALL 100 stop)
-> Print
-> tr :: TimeRange
-> Discard;

DriverManager(wait, save tr.interval -, stop)

---
countint.click:8: While configuring 'DriverManager at 8 :: DriverManager':
  syntax error at 'save'
Router could not be initialized!
---

Also out of curiosity I want to know why the script is printing 121 packets
instead of stopping at 100 (commented the DriverManager line in this case).
