Select item thru combobox to edit userform data

Hi everyone,
I'm preparing a sheet for my office, with two userforms.( I attach the file.)One to enter the data another to edit the data. In the userform to edit/amend I placed a listbox to choose item("Savings No"). It's working O.K.
But I want the same thru Combobox, which I'm not able to. Support is highly appreciable. Thanks in advance.
