Pass variable from module to the userform.

[alex009988]

Hello. How to pass variable from module to the userform, namely to texbox.
In order to do that I use that userform code, namely commandbutton code.

Option Explicit
Private Sub CommandButton1_Click()
addr = Form2.RefEdit1.Value
n1 = Form2.TextBox1.Value
TextBox2 = g1
'Unload Me
End Sub
....

And mudule code

Public g1 As Double
Sub Sim()
Form2.Show
g1=5
End Sub

And user form gives an output as 0 instead of 5.
Should I call sub sim somehow or...?
