I watched that video before I tried doing this. I want to display individual products from multiple categories. I tried using tags custom query and it helped but still not what I want. I couldn't get the name query to work, but I am not sure I entered the info right, that is why I asked about product ids.
When I use this query only the first product displays:
name=Mirage Stone Outdoor Woodburning Fireplace (Taupe)&Guardian Angel Statue w/ Solar Lantern& Double Rail Garden Bridge& Rooster Weathervane& Kate Collection Loveseat w/ Espresso Cushions& Ebony Ivory Collection Loveseat w/ Cushions& Bellagio Pergola& Luxe Hexagon 16 Pavilion with Sidewalls& Cook Number 36 Gas Grill w/ Deluxe Cabinet& Electric Cook Number Grill (Black Porcelain)& Patio Bistro Table w/ Granite Top 2 Chairs& Goletta Outdoor Fountain
I have tried several variations but no luck so far.
