How do I count a list column value and display the total in another list?

Question
-
Hi,
I'm sitting with the following conundrum in MOSS 2007;
- I have 3 lists, lets call them Project Overview, Project A tasks and Project A tasks.
- they are all custom lists where Project Overview only consist of two list items representing Project A and Project B (The Project Overview list serves as summary of all the projects with their various attributes, such as deadline description etc)
- The Project A tasks and Project B task custom lists are similar in design used to capture tasks items for each project. Each project list utilizes a simple task workflow, therefore I can determine when a Project List item is still open based on the workflow status.
Problem statememt:
How do I display the amount of open list items for each project in the Project Overview list in a column called 'Open Tasks'?
I know I'll be able to determine if a item is still open for a project list item based on a workflow status, but how will I go about calculating all the open items (adding them up) for a list and displaying it as a number value in the Project Overview list for each project?
I was thinking of creating an extra column in the Project Task lists and assign a 1 for In progress items and 0 for completed or Not started Items. However, How do I add all the 1s and display it in another list? Might this be possible with a workflow?
I'm not a developer so applying any custom developer solutions might be a problem.
Thanks in advance
