Newbie- Problem getting extendedData of parent node

Cheryl_Henry_(nswcdahladmin_-_(deleted))

Hi,I'm trying to customize the task module so that a continuous sequence of numbers are assigned to each task in a task list. For example, if I had two task list, List1 and List2, the tasks in List1 would have a number assigned to each one starting with 1 then 2 then 3 and so on. The same would happen for List2. The way in which I'm implementing it is by created an extendedData field in the task List that holds the last value given to a task. Storing the value in the Task List seems to work because I can print it out in a web file. The problem is when I'm trying to create a new Task and retrieve the parent's(Task List) extendedData. The extendedData doesn't seem to be there. Can anyone tell me how to retrieve this information?Thanks in advanceKecia
