CiviCRM Community Forums (archive)

I have a custom field for Contribution records and want to set its default pull-down list value to the value of a custom field in the individual's most recent active Membership.  After looking through the developer documentation I am still not sure how to begin structuring this into the CiviCRM, Drupal architecture.  Can someone point me in the right direction to get started?

(PS. The specific need is this:  Each individual membership has a custom "Chapter" field. When membership dues are received from individuals, a custom Chapter field is populated with the chapter of their membership.  This allows tracking of membership dues by chapter.  Currently, when offline membership dues are recorded, the administrator has to look at the individual's Membership tab, remember the chapter, then go to the Contribution tab, and select the same chapter when they enter a new contribution.  )

Thanks!
