I am trying to upload and execute the following three year old code (which was created on someone else's Salesforce developer console). I have the code but the execution/creation of custom objects etc. is confusing me and I cannot figure out how I'm supposed to do it - the guy who was supposed to help isn't responding and I'm on a tight deadline.
I tried uploading the code on dev console on Salesforce but apparently I have to create custom objects??? and it didn't even execute either and I wasn't able to create/access the web app.
Here is the link for the code: https://docs.google.com/document/d/1sTarJgRz5q3kjG2zizJp2n1H2X9D7XDV/edit?usp=drivesdk&ouid=113751617738626794754&rtpof=true&sd=true
