I am learning how to develop Skills with Alexa. I followed a Lynda course to build the My Calculator skill, however ran into a problem where the numbers and results are not returned. I double checked my code, and tried it on Echoism.io, and same problem. Per the attached, the numbers are recorded in the JSON input, however are not returned in the speechText or displayText?

What is the missing piece of code? Thanks.

Welcome Roy! Couple things. In the future just put your code right here on the page so that it becomes searchable and we can see the exact characters you are using.

By looking at the images it looks like to me the following might be your use of template literals. Super common mistake.

So to use template literals you need use the back tick (`) instead of the single quote (')

It looks like it is that you currently have

speechText = 'The result of ${firstNumber} plus ${secondNumber} is ${result}';

and what you want is

speechText = `The result of ${firstNumber} plus ${secondNumber} is ${result}`;

  • Thanks for your feedback! I'll try to cut and paste the code in the body next time. Didn't know back tick was a thing. It worked. – Roy Jun 22 '20 at 21:12
