For instance, I like to initialize my variables at the start (I pull the data element values using _satellite.getVar(), just so I can use a nice short name in the code) and I like to add try/catch to ensure that if something fails, it fails more gracefully. Then I determine in one chunk of code (for page level tracking) based on page type, what pixels will f...
