I need some work done on a drupal website. This is what I have so far:
I have two content types. One is "Event", and the other is "Expense". Events are created. After, the events are viewable in a view.
What I need:
I want users to be able to create up to one "Expense" per "Event". They should be able to view the "Event" in both views and on the content itself and "Add Expense". They should be only able to add one "expense" per event.
After that, I should be able to view all "Expenses" for each "Event".
As I said, the content types "event" and "expenses" are already set up. The views are also set up. I just need to build the relationship between then.
I am using Drupal 7.19
