how do i use the getcellrange method for the SelectData interface?  I've selected some cells in a general table and I wish to do some manipulation to those specificly selected cells.  Here is some of the code that i'm using.

Dim swApp As SldWorks.SldWorks
Dim swDoc As SldWorks.ModelDoc2
Dim swSelMgr As SldWorks.SelectionMgr
Dim swTableAnnotation As SldWorks.TableAnnotation
Dim swSelectData As SldWorks.SelectData
Sub main()

'Do some things in here.  Set up your objects, whatever.
Set swApp = Application.SldWorks
Set swDoc = swApp.ActiveDoc
Set swSelMgr = swDoc.SelectionManager

Dim BoxReturn As Long

Dim FirstRow As Long
Dim LastRow As Long
Dim FirstColumn As Long
Dim LastColumn As Long

''''**********
'This next line will show a for and the code will
'pause execution for as long as the form is
'visible.  The when the user clicks one of the
'form buttons the form will go away.
'The form has a bunch of code on it.  Don't even look at the code.
'All you need to know is the syntax of the line below.  It is
'as close as possible to the syntax for a MsgBox.
'''''**********

BoxReturn = YesBox.GoBox("Please select numbers for conversion, then press ""OK""", "Need Input", vbOK)

If BoxReturn = vbOK Then
    MsgBox "There are currently " & swSelMgr.GetSelectedObjectCount2(-1) & " things selected."
   
    Set swTableAnnotation = swSelMgr.GetSelectedObject6(1, 0)
    Set swSelectData = swSelMgr.CreateSelectData
    swSelectData.GetCellRange FirstRow, LastRow, FirstColumn, LastColumn

End If
End Sub
