Dynamic background image

Hello,
When posting code in the forum, please make sure to format it as explained here:

As for your question - you cannot use such code in your css files:

 background-image: url("http://vanderbundtcollection.com/carimages/'+serverconnect1.data.inventory_details[0].PhotoURL1");

You need to apply this on the element on the page, using the dynamic attributes > styling > style to do this.
