System.Windows.Forms? Add to the tags: "Forms". Do it; you are the most interested person to do it.
What does it mean: "moving the value" (learned COBOL before? :-)
What do you mean by "variable"? A class member or not?

This is the popular question about form collaboration. The most robust solution is implementation of an appropriate interface in form class and passing the interface reference instead of reference to a "whole instance" of a Form. Please see my past solution for more detail: How to copy all the items between listboxes in two forms[^].

I suppose you want to retrieve the value of variables in a form from another form, if that is the case then try this

Public Class Form1

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
Dim sure As Integer
Dim now As Integer
Dim yea As Integer

Form2.takeval(sure, now, yea)
End Sub
End Class

Now you can call it from form2 by.....

ublic Class Form2

Public Function takeval(ByVal num1 As Integer, ByVal num2 As Integer, num3 As Integer) As Integer
num1 = 5
num2 = 6
num3 = 7
Return num1 And num2 And num3
End Function

Private Sub Form2_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
End Sub
End Class

From that function in Form2 you can easily retrieve your values
