Dropdowns don't work

[hsaltan]

After deploying the DynamoDB table in Module 3, I tried to connect to the web page but the dropdown buttons don't work. This happens when I open in the browser using the S3 bucket website endpoint. The only response I get is a static page as below. If I add "mysfits" to the end of the endpoint as done in Module 1, this time I get a "404 Not Found" error as shown below again. This same issue repeats itself in "Likes" and "Adoption". I went over the .py scripts, resources deployed, the rules, permissions several times but I couldn't find the fix. What am I doing wrong?
