• As a data analyst, I want to analyse form submissions and page performance according to the campaign/basket/scope. 

Part 1: Push dataLayer values on page load

As right now, dataLayer values are fired on an event (form submission). We also need to see those values before the user signup. 

Observation: We need to test the dataLayer push to make sure that it can be read on page load and also on the event. 

dataLayer.push({

 'gCampaign' : '[value defined in Campaign field]',

 'gBasket' : '[value defined in Basket field]',

 'gScope': '[value defined in Scope field]',

 'gDepartment': '[value defined in Department field]',

 });
