VB coding for using excel userform to edit and overwrite an existing database

Dear All,

I've tried to make 2 userforms for a succession plan office project.

Userform1 (Data Entry)
1st part of the form extracts data from the "master database" sheet.
2nd part of the form is used to enter data into the "succession database" sheet.
This userform1 works perfect.

Userform2 (Data Edit)
This form is used to first extract and show the data entered into the "succession databse" sheet. The information is shown in textboxes and I expect the changes made in those textboxes will overwrite the existing initially entered information in the "succession databse"; but that's not happening.
I also wanted to have a combobox with just the employee's name to filter/dropdown and auto-retrieve the rest of the information but couldn't make anything happen so opted for the listbox.
The template is attached herewith with one hypothetical row of information. I need help on the working of UserForm2.

PLEASE HELP ME!
