Apple

I recently went through all the hassle of setting up a simple process which is to be designed so that selected images in iPhoto would be added to an album. I went with building up a service to be triggered in iPhoto proper. I stopped by choosing "Receives no input" "in iPhoto". When I select some iPhoto pics I see the name of my service appearing in contextual menu and once initiated it starts running but then aborts thus failing to achieve the expected goal - to add the photo to the album I want it to. The service consists of only one action "Add to iPhoto album". Please could I earn some your advice on what I did wrong? The problem is that the service is visible in contextual menu only when I select it not to receive any input data (which means I assign it manually to the type of data I desire).
