By the way, I'm using v. 10 on OSX 10.6, and I'm brand new to Filemaker
Thank you for your post.
With the database file active, pull down the File menu and select "Sharing -> Instant Web Publishing...". Next, turn on Instant Web Publishing (if it is not already turned on). In the bottom left corner, select the database file, and in the lower right corner, select access for "All users". Click OK.
On the same machine, launch your browser of choice, and enter:
http://<IP Address of machine>
For example, if the IP address of the machine is 10.10.10.10, the URL you would enter is:
If you are using another port other than the default port 80, then follow the URL with a colon and the port number. For example, port 591 is registered with FileMaker, Inc. If you change the port to 591, then the URL would be:
Regardless of the port, at this point, you should have the Instant Web Publishing screen displaying your file.
If you have a static IP address, then enter the same URL on another machine's browser. If the Instant Web Publishing screen doesn't display, then you may want to check with your Internet Provider about obtaining a static IP address.
If you are still running into difficulty, or if you need clarification for any of the above steps, please let me know.
