Hi, I use the full name button in my form. In the "thank you" and auto response email, I want to only use the first name, not first and surname.

Hi, I use the full name button in my form. In the "thank you" and auto response email, I want to only use the first name, not first and surname.  Please can you tell me how to do this?

If you are using the FULLNAME field and would like to display only the first name in your thank you page, just add FIRST after FULLNAME as shown below.

{fullName:first}
