Storing Access 07 Data On VB 08?

I've linked the two using the standard data sourcing method and I now need to use the data that is read in to it on another form. The idea of this is that I'm creating a wage calculator and the employees are stored in a database and can be viewed on a vb form, however, I now need to use the data of their pay/hr to be used on another form to calculate the wage.I have tried to declare a public variable across the two separate forms, and on the button that takes you to the other to set this variable as the contents of the text box which is displaying the pay/hr using the following

Public Class ManageUsers
Public HrlyRate As Decimal 'Declaring global variable to use between forms

'Some other code in between relating to rest of the stuff on the form

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
RatePerHourTextBox.Text = HrlyRate 'Saving private variable to global variable
Calculation.Show()
End Sub
End Class

Then on the other form I have used this code to do the calculation:

Public Class Calculation
Private Sub calculation_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

[code]....
