Task Dependencies

[Derick C.]

I want to link two tasks with the same duration so that when I change the
duration of one task, the duration of the second task updates automatically.
Both have the same start date.

Hi,
There is no "pure Project" solution.
Best way to achieve this is to copy the duration of the first task and paste
link it in the duration foeld of the second task.

You need a "hammock task". Copy the finish date of one task and then
use Edit/Paste Special/Paste Link to create a dynamic link from the
finish date of the other to that of the first.
