Need help in custom script

I am running
ERPNext: v6.27.15 :
Frappe Framework: v6.27.16

I developed a new app product master and a doctype inside the app with the same name product master .
i) I have three fields edger,blocker and finisher , i want to add all the three fields and display that in field named total.
ii) Then i do have a custom field named c_max this should not be lesser than a field named c_min .

My module and doctype share the same name product master.

Tried few custom scripts available in the internet , nothing worked . It would be of great help if someone could provide me a tutorial link on custom script syntax .

Thanks in advance,

Ragav
