Ok, I haven't received any advice to my previous post so I'm trying to do something on my own...

So, I thought that I can create few Command Buttons on UserForm and every one of them will make different form on document appear. First I tried to create one checkbox by command button.

Private Sub CommandButton1_Click()

Selection.FormFields.Add Range:=Selection.Range, Type:=wdFieldFormCheckBox

Selection.TypeParagraph
    
End Sub


And i got this error in the highlighted line above :

Run-time error '4605': This command is not available
Any advice ? :D I use Word 2003
