When pasting your code use the preformatted text option (< / > icon at the top of the editor). This keeps your formatting and will make it easier to determine things like spacing issues.
Do you see any errors in the home-assistant.log? This log file should be in the same folder as your config.yaml or if you click on the circled “i” in the dev tools section you can see the log there.
With some additional info I’m confident someone here can help out.
