28 Trim()

The code on page 28 will not remove any additional spacing. A better example of the code, which will remove any additional spacing and not allow empty strings, is:

Dim Greeting
Dim UserName
Dim TryAgain

TryAgain = "No"

UserName = InputBox("Please enter your name:")
UserName = Trim(UserName)
If UserName = "" Then
MsgBox "You must enter your name."
TryAgain = "Yes"
Greeting = "Hello, " & UserName & ", it's a pleasure to meet you."
End If

Loop While TryAgain = "Yes"

MsgBox Greeting
