If you are using an iPad or other tablet computer to modify the worship flow, you can do so in the mobile version (which is where you should be routed by default).  But if you wish to do so on the main Service Planning site, we recommend the following technique to drag and drop items:

1. Tap once on the item you want to drag (try to avoid touching the text on the area, as that may open a window with more info on that item)
2. Touch and drag the item to the appropriate place
3. Drop it by lifting your finger from the screen
