I have created a simple but effective Automator Action that I am using to call scripts in Filemaker (with an optional file as a parameter). It can be used in a variety of ways, but I primarly use it to add files to containers. The action uses the newish Filemaker URL format, so FM 12 or 13 is required. I am sharing it here in case others might find it useful.
This automator action was inspired by FullCity Consulting's wonderful Snap2FM implementation. The automator action allows other scanners to directly feed into Filemaker in a fairly simple manner.
