I got the Sunpak Flat Panel Flash and I attached it to my DRebel's hot shoe adapter. However, when I hit the shutter the Sunpak is not triggered. Even tried automatic setting on DRebel.
Is there a setting on the camera or do I need cord between the Sunpak and DRebel? The Sunpak comes with a sync cord but you can't attach it to the DRebel.
