how can i give a link to one user form to anther user form

Simple solution is to set some global variables in your main Macro Module
public Label1, Label2 as string

Then in your First userform Terminate event, initialise the second Userform

In the second Userform initialise event read the two global variables.

Then in your Second userform Terminate event write the date and time.

I have tested this for you and basically it works. I had to hide Userform1 before showing userform2
and then unload userform1 in the terminate event for userform2

I went a bit further and created a textbox on userform1 to show the time.
I had to use ontime for this. and Quit to stop the timer.
