For instance I want to track the purchases of customers with Conversion Tracking in e-commerce sites. Because the total cost varies from customer to customer I should include a code in the conversion tracking code that Google gives me, right? For ASP the dynamic variable is <%=totalValue%> For PHP the dynamic variable is <?echo $totalValue?> I want to exactly know how to use the code? I gave a stable value $200. if (200.0) { var google_conversion_value = 200.0; If dynamic should be inserted on ASP E-commerce customer basket if (<%=totalValue%>) { var google_conversion_value = <%=totalValue%>; is this code right? And I want to learn some practice for using funnel on Google Analytics. Is there any active topic about this?
