How to activate a Layout Based Form

@daniel
Thanks for your response.
I do not think there is a need for clicking update in forms administration. That segment is for predefined openemr forms and not for self designed Layout based forms.
Layout based dont appear there, ( i may be wrong anyway)
However, moving forward, i have pictorial images of layout based segment and also indicated
the portion where u can uncheck the active box.
The problem now is after unchecking the box, the form will no longer be available in layouts under admin module.
The question is how can the form be reactivated.
