The first error is because the general outer layout has the 'Google Analytics Tracking Code' at the foot of the page whereas in the receipt page, this code must be in the header.
The solution, is to move the following code: -
Code:
<actinic:variable name="GoogleAnalyticsMarkup" value="Google Analytics Tracking Code" />
The second error can be resolved by going to 'Design | Library | Layouts' and scrolling down to the 'Web Page Inner Layout' and opening the layout 'Receipt Page Bulk RWD'.
Scroll down to line: 60 where you should see: -
Code:
window.uetq.push({ 'gv' : NETQUOTEVAR:ORDERTOTALBASEUNIT, 'gc': 'GBP' });
Code:
window.uetq.push({ 'gv' : 'NETQUOTEVAR:ORDERTOTALBASEUNIT', 'gc': 'GBP' });
