Copy the code and paste it into a comment. You can read how to format it by using the Markdown Cheatsheet link just below the textarea where you type.

Thank you for sharing the code. What are you experiencing on Chrome? Does you get the prompt showing at all?

This JSFiddle worked for me.

It is possible that Chrome is preventing additional dialog boxes. Try some of these solutions.

Just a couple of questions/comments: is the students array in the students.js file or below the rest of your code in student_report.js? If it's repeated in student_report.js, the variable students from the students.js file will be overwritten.

Also, because the code for generating the student reports HTML and printing it are outside of the while loop, you have to quit before you will see the results.
