ESP32_POE_ISO thermometer code using ssd1306 display with pages and SHT31

Hello world,
Could someone please do me a solid and check my .yaml?
I’m still learning and are having trouble with using pages in the display block.


The error is:
←[32mINFO Reading configuration esp_poe_iso_sht31_pages.yaml...←[0m
←[31mERROR Error while reading config: Invalid YAML syntax. Please see YAML syntax reference or use an online YAML syntax validator:

while parsing a block collection
  in "esp_poe_iso_sht31_pages.yaml", line 48, column 7:
          - id: page1
          ^
expected <block end>, but found '<block sequence start>'
  in "esp_poe_iso_sht31_pages.yaml", line 59, column 8:
           - display.page.show_next: my_display
           ^←[0m

And the .yaml in question is…

display:
    platform: ssd1306_i2c
    model: SSD1306 128x64
    id: my_display
    #reset_pin D0
    address: 0x3C
    rotation: 0°
    pages:
      - id: page1      
        lambda: |-
          if (id(temperature).has_state()) {
            it.printf(10, 0, id(my_font), TextAlign::TOP_LEFT, "%.1f°", id(temperature).state);
          }
      - id: page2
        lambda: |-
          if (id(humidity).has_state()) {
            it.printf(10, 0, id(my_font), TextAlign::TOP_LEFT, "%.1f°", id(humidity).state);
          }
        on_...:
       - display.page.show_next: my_display
       - display.page.show_previous: my_display

     # For example cycle through pages on a timer
     interval:
       - interval: 5s
         then:
           - display.page.show_next: my_display
           - component.update: my_display

Thanks and kudos for any help1

Indentation is all wrong in those lines.

Also on_... has to be on_something
