Update list of tasks in several sheets based on "Master-list" in sheet A

[Jacob2010]

Hi guys,

Im currently constructing a project plan and was wondering whether someone here could help me out for a sec. I have a list of activities/tasks in Sheet A, which I use as an input sheet containing activity details, estimates etc. Activities are located in column A.

On another sheet B, I have a project plan where I can track progress of the activities using a gant chart (activities are listed in column A here as well).
My problem is that I'm not really sure how to make the activities in sheet B update as I add activities/task list in sheet A.

Example:

Sheet A- Column A - activities:

A1:Do laundry
A2: Clean the house
A3: Walk the dog

Lets say I want to add a task between A1 and A2 in sheet A (entry in italics);

A1:Do laundry
A2: Wash my car
A3: Clean the house
A4: Walk the dog

How can I have excel to insert a row in sheet B and update the list of activites here as well?

Hope everything is clear, thanks!

Have a great day.

Jacob
