passing variable from userform

I am using the following code to open a userform. Once the userform is open, the user has the option to choose a continue button or a cancel button. If the user is choosing continue, the code is not working (it always skips to the "else" portion of my "if" statement. I can't figure out why it is doing this. Thanks. I have attached a sample of workbook, if needed.

Sub UpdateMasterFile()

Dim Continue As String

    Load DisclaimerForm
    DisclaimerForm.Show
    
    If Continue = "Yes" Then
        'do some updates
        MsgBox "Update Complete!  ", vbInformation
    Else
        MsgBox "Update Canceled!  ", vbInformation
    End If

End Sub

Userform code:

Private Sub CheckBox1_Click()

    If CheckBox1.Value = True Then
        ContinueButton.Enabled = True
    Else
        ContinueButton.Enabled = False
    End If
    
End Sub

Private Sub ContinueButton_Click()
    Unload DisclaimerForm
    Continue = "Yes"
End Sub

Private Sub CancelButton_Click()
    Unload DisclaimerForm
    Continue = "No"
End Sub
