vb.net form won't save value

I have a form that I open up to get a file name to save to.
Pretty much, it is just a text box with a few buttons.

On the form, I have a variable

    Public saveName As String

I have a save button which puts the textbox.text into the variable above

    Private Sub BtnSaveAs_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnSaveAs.Click
        If Trim(txtSaveAs.Text) = "" Then
            MsgBox("You must enter a name first")
            txtSaveAs.Focus()
            Exit Sub
        Else
            saveName = txtSaveAs.Text
        End If

        canceled = False
        Me.Visible = False
        'Me.Hide()

    End Sub

The main form that calls the second form, then asks the value of the textbox.

    Public Function getText() As String
        getText = Trim(saveName)
    End Function

For some reason, when the main function calls getText, the value of saveName is nothing.
I got rid of the me.hide because I though that was the reason.

after you instantiate form2, do a form2.showdialog() instead of show.  Make sure you set up your settings in form 2 to be a dialog and set your button press to be the OK button in your dialog.

What version of VB.NET?  2002/3 or 2005?  In the former, you will have to reference the specific instance of Form2, which would have to have been declared with New, to get any value from it.  In the latter, you can use a generic reference to the default instance of the form - which would not have been declared with New.  So how is the second form declared/called?  And how is the first form referencing it when it seeks to get the value from it?

To make the above comments more clear.

You issue is that you are getting multiple instances of your form for each variable you are using to reference the form.
So the second time you are dealing with a new instance of the form, which does not have the value that was set in your first instance.
