PowerTools does not do the variable substitutions, these are done by
Fox when the form gets submitted.
use either
NewPageName: {$(serialname MyGroup MyPageBaseName- )}

or change your form to

(:fox nlform template=Form.MyTemplate:)
(:input hidden pagename  '{$$(serialname MyGroup MyPageBaseName- )}':)
(:input hidden target {$$pagename}:)
(:input text pagetitle size=40:)
(:input submit post "Submit":)
(:input end:)
(:foxend nlform:)

or shorter:
Form:
(:fox nlform template=Form.MyTemplate:)
(:input hidden target '{$$(serialname MyGroup MyPageBaseName- )}':)
(:input text pagetitle size=40:)
(:input submit post "Submit":)
(:input end:)
(:foxend nlform:)
Template:
(:title $$pagetitle:)
PageName: $$target
