Help with setting/getting variables in app

Question

Hi,
I have an application which behaves in the following manner:
1. User logs in.
2. User is presented with a list of projects; user clicks on a project to drill down to that project.
3. User is presented with project information which includes 4 separate lists of tasks grouped by week. So there are tasks for the current week the user is in plus task for the 3 weeks out.
4. User can edit talks or create new ones for each of the 4 weekly groupings.
Given that, on the main page for a project I have set up a report and form for each of the weekly groupings. I also have an item for the project id as well as each weekly grouping id. The goal there is that when a user clicks the "create" button they can create a new task for the appropriate weekly group. However, this isn't working.
For the first weekly group when I click "create" I'm presented with the form to fill out for the task. All of the info is there, including the correct id for that weekly group so the task gets assigned to it properly. However, when I save I get an error which says that particular id is null.
For the next three groups when I click "create" I'm given the same thing as above but without the id for the weekly group. Even if I set it and save things I'm getting the same error.
So, I'm wondering what I've done wrong in the app flow. Am I setting these variables too early, too late? Am I really not picking them up in spite of what I see on my screen? Have I missed some fundamentals of Apex here?
Thanks in advance for your time and help.
Jon
