Implement the score processing 5. In the index.php file, add code that calculates the score total. When you're done, clicking the Process Scores button should display the correct total and average. 6. In the index.php file, use a for loop to validate the user entries instead of using multiple conditions in a hard-coded if statement. 7. Test your changes to make sure they work correctly. Modify the roll processing 8. In the index.php file, modify the code that processes the rolls so it uses a for loop as the outer loop instead of a while loop 9. In the loop tester.php file, use a for loop to display the " tags for the drop-down list instead of hard-coding six"" tags. 10. Test your changes to make sure they work correctly
