VBA If statment confusion

The below code worked fine until I added the code for the vbokcancel bit... code below:

If Me.results.ListIndex = -1 Or Me.userfolder.ListIndex = -1 Or
Me.choice.ListIndex = -1 Then           

MsgBox "Please choose something to remove"

Else

If MsgBox("Are you sure you want to delete this user from this folder?", vbOKCancel) = vbOK Then

    If Me.choice.Value = "Folder" Then

        username = Me.results.Column(0)
        prfolder = Me.results.Column(3)

        strSQL = "DELETE tblRelationship.*, tblPra.praNo, tblFolder.folder FROM tblPra INNER JOIN (tblFolder INNER JOIN tblRelationship ON tblFolder.folderID = tblRelationship.folderID) ON tblPra.praID = tblRelationship.praID WHERE (((tblPra.praNo)='" & username & "') AND ((tblFolder.folder)='" & prfolder & "'));"
        CurrentDb.Execute strSQL
        Me.results.Requery

    ElseIf Me.choice.Value = "Username" Then

        prfolder = Me.results.Column(0)

        strSQL = "DELETE tblRelationship.*, tblFolder.folder FROM tblPra INNER JOIN (tblFolder INNER JOIN tblRelationship ON tblFolder.folderID = tblRelationship.folderID) ON tblPra.praID = tblRelationship.praID WHERE (((tblFolder.folder)='" & prfolder & "'));"
        CurrentDb.Execute strSQL
        Me.results.Requery

    End If
  End If
End If

It will activate the If MsgBox("Are you sure you want to delete this user from this folder?", vbOKCancel) = vbOK section but if the "OK" button is clicked it skips straight to the End If and does not run the code within the IF statement. Now I thought what I did was perfectly "Legal" in coding, apparently not... any ideas what I've done to screw up?

If you press "Cancel" it does what I already want it to do, which is close the message box and the user is back at the same screen.. so there's no need for an Else statement because it already does what I want it to do.
