Using Smart FTP and Frontpage. Need Help!

I have recently had a friend create a website for me and he has now handed it over to myself and partner to update. However we seem to be having to problems. We have to use Smart FTP and frontpage. I have been able to download our links page and update through frontpage and then upload it back through smart ftp no problems. However now I am trying to update other pages within the website and it does not seem to be updating. It goes through the correct process - downloading and uploading but nothing happens on the site. Can anyone advice please??!!
