Deleting Shared Objects from server

[faeryking]

I can update the object with the following code:

_root.entries_so.data[pictureID].title = "Updated Text";

If I do any of the following the shared object gets corrupt and I can no longer add to it.

_root.entries_so.data[pictureID].title = null;

or

_root.entries_so.data[pictureID] = null;

or

delete _root.entries_so.data[pictureID];

Do I need to do this server-side in the main.asc and how would I do that??
