Input Field Response is missing on email notifications because of a typo

Can you tell me why the response for the "Main Color" field is missing on my responses for the following form? The question appears in the email notification and is a required field but the answer does not appear.

The problem was a typo in the main color unique name in the notification email: it had an additional "9".

You can see in the animation, step by step, how I identified the correct variable and then corrected it in the email notification:

1. We click on the element "Properties" then we go to the "ADVANCED" section.

2. We click on the "FIELD DETAILS" button. This will show us the "UNIQUE NAME". We notice here that it's "whatIs".

3. We go now to the email notification section, where we find that we've been using "whatIs9" instead.

4. We correct this typo and save.

Please let us know if the problem still persists, or if you need more details. I also created a corrected form for you in case you want to clone from it: https://form.jotform.com/63463620161954

Thank you so much! That was a fabulous explanation! I will now know to look for that in the future! You guys ROCK!
