I have tried several time to install the following steps in order to get the ‘simple site search’ working in FWPro 6:
1 - add the Simple Site Search as a Folder action to the site folder
2 - select a form search field and then Item>Actions>Simple Site Search
3 - on a page in your site Insert>Action>Simple Site Search (creates an HTML box to display results)
After having these stamps don I tried the site search on the live site. It worked once. after doing a next site search nothing happened, no response at all.
