Hi Akshay, 
 There are more then one way to do this activity 
 One way is when user fills the first name in the firstname field and last name in lastname field then we can populate the email in the email field by using user finction as: user(touniformstring(index(usersearch({"firstName","lastName"},{1,1},{"firstNamevalue","lastNamevalue"}),1,1)),"email") 
 
 Another way is you require the email in the same field where you are typing the firstname and lastname, the you need to create a custompickerfield. 
 
 I hope this will help you
