As you see in the picture under this text, i have a doctype wherein i can select a client (1) and a contact (2).
Each client has 1 or more contacts.
When i select the contact, the other fields (3-7) are filled in automatically.
I only have one problem with this: when i have selected a client, i see all the contacts.
How can i filter them to only show the contacts from the selected client?
