I have a created a Site and four different subsites. This is just to give the big picture although the four subsites has got nothing to do with the problem as far as i know. When i created the Main site by default there were two SharePoint Groups for Viewers, members and Owners. There are around 20 users added to Members and 4 in the Owners and 1 in Viewers.
Now on the Main site i created a custome list with 5 columns. one of those has a Trader Column that uses the type "Person or Group". I did a edit column on Trader Column and moved down to "Choose from:" that gives me two options
1. All Users
2. SharePoint Group.
I have created a New sharePoint group to include only the Traders. So far so good theoritically.
However when i chose the second Option "SharePoint Group" and in the drop down i chose "Traders" group. and click OK.
now i have created a DataSheet view so the Traders can enter their Trade data. So far so good again IMO.
Now when the I try to test by selecting a Trader in the Drop Down (for column "Traders") it lists ALL the users ever created in the Entire Site whereas it should be only showing the users under SharePoint group "Traders". Why is that? What is that i am missing. I am being pressed with my own responsibility to figure this out. Any help can be of a Great direction for me.
