The information may look a little different to people using different hosting companies, but usually the information would look similar to this:
Server / Host Name:
Only you will know the answers to the last three, but it is likely that the first one will actually be 'localhost'.
If it isn't, you could try www.marylingerie.com, and if it isn't that, then you will need to find out from your hosting company what it is. But try 'localhost' first!
Hope it works out for you, - post back if you still have problems.
