Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

No bugs.

  1. Assuming you've left the project's "hours per day" at the default value of 8, then your critical slack threshold of 6 days is 6x8=48 hours.
  2. On the two tasks selected, the Total Slack is 2.63 elapsed days x 24 hours per elapsed day = 63.12 hours.
  3. Since 63.12 > 48, the two tasks are not Critical.
  4. For these tasks to show as Critical, you would need to increase the critical threshold from 6 days to 8 days (i.e. 64 hours).

In this case, your true Critical Path might be difficult to discern without tracing the driving logic.

Good luck, tom
