Hi James,

I think you want to surround temperature with brackets rather than inverted commas else it will be treated as a string, not a variable. So, you want to alert with the value Math.round(temperature) (don't forget the capital 'M').

OK with that? Let me know how you get on.


Hi steve,

Thanks for the advice. Silly on my part, really, left out the capital M and managed to resolve it with the below:

alert (Math.round (temperature));

Thanks again

Spot on - good work! :smile: :+1:
