Getting data from a blog subsite loaded into a slider

I'm using the webURL property to change the list location and get a couple of fields from a child blog site (to populate a slider on parent site home page). The slider works fine when pulling from a list in the same site, but not from a sub site.
I've tried:
different formats for the url - relative/absolute;
the posts list in the blog and a custom list added to the blog site;
adding the url as a variable;
It seems it just isn't reaching the sub site. Any tips?

Update: I was able to get this to work using a custom list in a subsite so can confirm it only seems to affect the "posts" list in blog sub sites. Wondering why this type of list acts differently?

Figured it out - I wrongly assumed sliderList should equal the original list's name: "posts". The list was renamed "articles" at some point, and that works!!
