Hi Team,
currently I have a custom logo displayed in my survey based on the "LogoURL" embedded data which is a dynamic url for each of my locations.

I have been asked to also apply a custom background image for each location as well and despite looking through the existing posts I cannot seem to get one to work!
Can you please advise what coding I could apply in the header of the survey to apply a custom background image for the whole survey based on the url value in the embedded data field, ie: BGURL
Thanks
Paddy
