Before your selection will appear on the public web site, the festival director must enable the display of this year's selections. They may be waiting for a certain number of selections to enter their data.
If you have made a change and your selection is already on the site, your page will re-generate after a few minutes. Your browser, however, will likely retain a cached copy of that page. You may therefore have to flush your browser cache in order to see the changes you made.
