Additional Problems Sharing Folders over Network...........

Ok, I am getting increasinlgy frustrated with w7 and it's sharing of folders and such..... I have one folder it is my music. I want to share this as a network share and I open the network tree I see my PC Name and under it is the above folder my music. I right click on this folder and navigate to Share With.... Here I see my PC name and that's it. I then enter everyone and click/read/write. Thinking I have now shared this folder I go back and everyone is gone. I then right click this folder > properties and sharing, advanced sharing. Here I click permissions and I verify everyone is enabled with full control. At this point I still can't share this folder over my network?? I am the owner of this PC and its contents. Am I missing something in my steps above? Thanks!!

Well, my messing with W7 and its crazy sharing properties now leads me to the following errors:

You don't have permission to access this folder/ click continue to gain access/ you have been denied permission to access this folder/to gain access use security tab... I do this and its prompt after prpmpt of permissions. I am at my wits end with this. I am the owner of this PC and all its contents! This should not be this difficult. Any suggestions? Thxs
