Thank you for your post.
What version of FileMaker Pro are you using? When I use FileMaker Pro 10 on Mac OS X 10.5.8, I can insert a .mp3 file as QuickTime, and it displays a speaker icon, play button, along with backward and forward icons, and I can play the song. If you instead use Insert File, then it will display the file icon, but you will be unable to play it.
Thanks for your reply. I am using version 10.0v1
I upgraded to 10.0v3 but it still doesn't show. I wonder if it's because I'm on 10.5.4
Ok I've upgraded to FM 10.0v3 and OS X 10.5.8 but I still don't see a speaker icon or any other icon when using Insert Quicktime and loading an .mp3 or .wav file. If I click on the container field I do indeed see player controls and I can play the file. But I need to be able to see whether or not a file exists because the field appears blank even though a file is there.
