Visual Basic: Combining Two Input Fields

Please help with the following problem. I’m lost in where to enter the other function to combine the two fields to prompt the user for last and firs name.

The problem is given below:
Expand the program by adding another function that asks the user his/her age. Output both last name and age in the Main procedure. (Paste your code below)

Module Module1

Sub Main()
Dim lastname As String
lastname = GetName()
Console.Write(“Your last name is ” & lastname)
Console.ReadLine()
End Sub

Public Function GetName() As String
Dim name As String
Console.Write(“Input your last name? “)
name = Console.ReadLine()
Return name
End Function
End Module
