Hard-rejected again. I don't understand.

Not sure why this JavaScript widget was rejected. Here’s a demo: http://gpa-calculator-test.s3-website-us-west-2.amazonaws.com/

This is the second time I’ve been rejected without any explanation.

We have completed our review of “GPA Calculator” and unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.

Starting to feel like I’m wasting my time here.
