importing svn problem

Hello there. I am an svn newbie and wanted to ask about trying to import an svn into assembla. I tried the import svn option but cant see anything at the svn link just a page with revision 0 on the top with no history or folders in there. Please advise as to how i can import a .tar.gz file into here.

Open trac admin tab, be sure you are logged in to trac.
Select Import/export menu from the left
Submit your svn archive to svn form.
