Problems with scrape

I’m trying to setup some sensors with scrape, but cannot get them to work.

I have the following configuration:

    - platform: scrape
      resource: http://[URL]/
      select: "#ctl00$ContentPlaceHolder1$Booking1span1"
    - platform: scrape
      resource: http://[URL]/
      select: "#c5167 .tx-dmi-data-store div tabke tbody tr .Broedtekst"

But I get the following error in HA:
