Using The Text From A Textbox In A UserForm

I think I have broken the back of programming OptionBoxes and
ComboBoxes in userforms but am trying to use the text entered into a
textbox. I have the text box to initially show "x" but want the user
to change this and then save it to a variable. I can get round this
by using the .controlsource referncing a cell but want to use a
variable instead. This is my code:-

Dim Tempform
Public NewTextBox As MSForms.TextBox ' In Declarations
Public c as String ' In Declarations
Dim X As Integer

Set Tempform=ThisWorkbook.VBProject.VBComponents.Add(3)
Set NewTextBox=TempForm.Designer.Controls.Add("forms.TextBox.1")
With NewTextBox
.text="x"
End With

Set NewCommandButton1=.........("forms.CommandButton.1")

With Tempform.CodeModule
X = .CountOfLines
.InsertLines X + 1, "Sub CommandButton1_Click"
.InsertLines X + 2, " c=NewTextbox.Text"
.InsertLines X + 3, " Unload Me"
.InsertLines X + 4, "End Sub"
End With

This always gives me c="x". Can anybody tell me what I am doing
wrong?
Thanks, as always!

As an addition to the above I do show the form using
VBA.UserForms.Add(Tempform.Name).Show

As usual..post a question and then immediately sort it out!
.InsertLines X + 2, " c=Textbox1.value"
works!
