Hey forum

Have running project from 26.10.2009 to 29.10.2009
Project has 21 tasks with different lenght.
Connection of all is end to start.
Have store project as base schedule
Work in window monitoring
Task 8 is working at the moment.
Tasks 8 have start 9 days later as planning.
All other tasks 9 to 21 also 9 days later, its clear.
The await tasks 9 to 18 all blue. The await tasks 19 to 21 are red.
I learned red are critical ?

I don't understand why only 19 to 21 are red ?

Can someone help me ?

Thanks.
