Edit/Update Data on A Range Using ComboBox

[fakehealer]

Good Day!

I Knew there should be a short code with this excel vba i have attached below
What I did on my attached file excel vba is a long coding method because i dont know how to do it using range code.

Scenario:

Whenever i choose name using combobox it will display on txtName.text for Name chosen
and respectively display txtNumber.text for Student Number
What i want is that i want to edit that name on txtName.text and edit also the txtNumber.text into a new data
replacing the old data by my new Input

When I click cmdUpdate button the chosen name will change in accordance with my new input

i have added the long code in my attached file and it works but i dont want to code it in a long method
I just want help how to have a short code with this!

Thank You So much and have a nice day Ahead
