Change values of labels in a userform through another userform

[Zhennie]

Here is what I'm trying to do: Let's say I have a simple userform with labels as follows:

(Label1) John's birthday: (Label2) 12.10.1974
(Label3) Mary's birthday: (Label4) 15.03.1978

(Button1) Change Birthdays

Let's say want to change the birthdays I see, so I press the button and enter the new values through another userform with inputboxes.

How do I make that change permanent, so that next time I start the macro in the labels 2 and 4 I have the last entered values for the birthdays???
