First Name in Email

I'm trying to call a person's first name in the confirmation email. It worked originally when I used {Name:first} but I changed the name filed to Your Name. So now I have {yourName:first} and it doesn't work. Any ideas?

Hello @summitmn,

Thank you for contacting JotForm Support.

I reviewed your form and I found that the unique name of the "Your Name" field is actually {fullName}. So, the correct way to get the first name would be {fullName:first}

Here is a screenshot of your form for reference:
