How do I get my Player Name Submission to Alphabetize by last name ?

In the submissions view it is not possible to Alphabetize by the last name, however, you can create a report that provides the option to sort the Players in alphabetical order based on the last name.

The HTML Table Listing Report displays this in a well-designed interface and creates a shareable link. Refer to this guide: How to Create HTML Table Listing Report. To sort the names based on the Last Name simply click the title of the Last Name field.

You can also create other forms of reports that have a similar option available.

Refer to this guide: How to Create Form Reports in JotForm
