Help fixing this error?

[learningtoprogram]

I'm just beginning to learn how to program and am going through a tutorial right now. I have had no problems up until this point. It is having me assign textbox text to my variables; however, I just can't seem to figure out what is wrong... Here is the code.


Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Dim FirstName As String
Dim LastName As String
Dim FullName As String

FirstName = txtFirstName.Text
LastName = txtLastName.Text
FullName = FirstName & " " & LastName
txtFirstName.Text = FullName

txtFirstName.Text = FullName
End Sub
End Class


The part that is giving me trouble is the line: txtLastName.Text and this is a screenshot of the Form.


Thanks for any help on how to figure this out! Here is the website I'm learning from if the information I gave isn't enough to help. http://www.homeandlearn.co.uk/NET/nets1p14.html

From what I can see there's nothing wrong with your code provided the full name should be displayed in txtFirstName.
You use this line twice for some reason:

txtFirstName.Text = FullName

but it changes nothing.

What exactly is the problem?

P.S. You don't need FirstName and LastName variables in an example this simple. Just:

 txtFirstName.Text = txtFirstName.Text & " " & txtLastName.Text

Generally though your interface lacks the third textbox. A good user interface should not change values in the user input textboxes. Ideally, you should add another textbox txtFullName and display the result there.

"The part that is giving me trouble is the line: txtLastName.Text ..." What sort of trouble? Your code is different than the lesson you posted, FWIW.
