Thank you for your post.
The Sort command will sort the records in the found set. Therefore, you need to find the records first prior to sorting. To Find the records, pull down the View menu and select "Find Mode". Enter the criteria for the records you want displayed. For example, you may put "FileMaker" into the Company field, and this will find all records where "FileMaker" appears in the Company field. Then, pull down the Records menu and select "Sort". Select the Last Name field (and possibly the First Name field) and sort. You will now have all "FileMaker" records sorted by the Last Name.
There are several different report options. Pull down the View menu and select Layout Mode. Pull down the Layouts menu and select "New Layout/Report...". This will walk you through the steps of creating a report.
If you need clarification for any of the above steps, please let me know.
