You can do this a couple of ways.
1. Because you're using a module make a variable.
Public UserName As String
Form 1
Private Sub cmdNextForm_Click()
UserName = Trim$(txtUser.Text)
Form2.Show
Unload Me
Exit Sub
Form 2
Private Sub Form_Load()
Me.Caption = "Welcome " & UserName
Exit Sub
or
2. Just put the name in the titlebar before you show the form.
Form 1
Private Sub cmdNextForm_Click()
Load Form2
Form2.Caption = "Welcome " & Trim$(txtUser.Text)
Form2.Show
Unload Me
Exit Sub
