Automate timeline for a series of events in sequence?

I'm working on a project that have many subtasks (module 1, 2, 3 etc in the attached screenshot) and many sub-subtasks (subtask 1, 2, 3 etc).  Because these sub-subtasks are sequential, I tried to figure out a way to automate the timeline, meaning any delay in subtask 1 (start2 in the screenshot) will cascade in all following subtasks.  I tried to use a function of Start 3 (=Finish2 + 1), but it didn't work.  

I'm dealing with about 25 of these tasks, so the manual process will be repetitive.  Any suggestions welcome!
