am kind of new to tkinter but i don't know what am doing wrong, i have already defined the function for attributes that would be inside the entryboxes but known are appearing after i ran the code. that is How do I bind the select make combobox so it can autofill the relevant entry boxes from the constructed vehicle class?

I see two main problems
you forgot some StringVar variables - ie. NoofDaysRenting and InvoiceID
you forgot to use textvariable= to assign StringVar to Entry - ie.
self.txtKmL = Entry(..., textvariable=self.KmL, ...)
so it doesn't update Entry when you update StringVar
Code after other changes.
It has textvariable= only in two Entry because there is too much work for me.
