To make the form available to be filled out, the form needs to be published. You can create or modify the form in three different locations. The options available are described in more detail but they are shown in Figure 9.28. If the Enable this form to be filled out by using a browser option is grayed out, then either the site doesn’t have the Office SharePoint Server Enterprise features enabled, or this form hasn’t been designed to be browser compatible. If this option is not selected, the users must have the Office InfoPath 2007 client available on their PC to fill out the form.
