Newbie needs help controlling Quicktime files from within Filemaker

I know this is really easy to do (right?) but I’m a total scripting newbie and I can’t find the information I need in my (probably inadequate) collection of references.

I have a Filemaker database. Each record contains three fields:

  1. A text field, which stores with a path name to a Quicktime file (myDB::pathname)
  2. A time field, which stores a “start time” (myDB::StartTime)
  3. Another time field, which stores an “end time” (myDB::EndTime).

I want a script that will call up the file stored in pathname, play it from StartTime to EndTime, and then pause.
This should be easy, no?
Can someone help?
