VBA - Insert Values from listItems to textbox

[Lucifix]

I have created UserForm where you can insert text/numbers to texboxes. Values in textboxes are saved in zzz.xls file.

On top of the UserForm I inserted listItems which shows data saved in something.xls files.

I would like to know how would I insert values in texboxes values from file something.xls?

I made screenshot how it looks.


Thank you!
