I have one last problem with this code....
1. You can see the code here https://drive.google.com/open?id=1uZAdMSnw0QrfjJbhijqeDu2NQTk5wFi4
click on page.html
2. Page loads and you see the radiobutton checked
3. Click on Add and another row is added but now, the first radiobutton is unchecked.
4. I checked the "id" and "name" and they're unique. Not sure why this is happening. I'll continue working on it. If I figure it out, I'll post back.
