How was the file inserted into the container? Was "store a reference" specified?
What storage options were selected for the container field? Are you using external storage?
What version of FileMaker are you using? (FileMaker 12 and 13 have the option of using an interactive version of a container field....)
How can I have an audio file that will stay with new forms. For instance when a new record is created the user can push a button that will play an audio file that gives instructions? I have received suggestions of using a floating document window to achieve this. I tried but when you attach that script to a button it opens a new filemaker pro window. The goal of this is to create an interactive kiosk for the iPad. I can't have the button to play audio open a new window as that destroys the kiosk experience. Any more suggestions?
