Add days to a DT variable based on NumericUpDown value

[JuggaloBrotha]

I'm using a NumericUpDown control and I have a DateTimePicker control that holds a date

what I need done is when the NumericUpDown control's value changes I need to show a date in a label that is # days higher than the date in the DateTimePicker

I'm using the NumericUpDown's ValueChanged event which does fire everytime the value changes, except this only works the first time the value changes, the code executes but it does not produce a new date in the label after the first value change.
Here's the code I have so far:

    'dtpDateOut is a DateTimePicker
    'nudDaysBack is a NumericUpDown
    'lblNewDate is a Label

    Private Sub nudDaysBack_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles nudDaysBack.ValueChanged
       Dim newDT As DateTime = dtpDateOut.Value
       newDT.AddDays(nudDaysBack.Value)
       lblNewDate.Text = newDT.ToShortDateString
    End Sub

Never mind, I neglected to see that newDT.AddDays(##) is a function, not a method. The code is:

            Dim newDT As DateTime = dtpDateOut.Value
            lblNewDate.Text = newDT.AddDays(nudDaysBack.Value).ToShortDateString

You have to catch the return value of the AddDays function:

[B][COLOR="DarkGreen"]newDT [/COLOR][/B]= newDT.AddDays(nudDaysBack.Value)

or even shorter:

lblNewDate.Text = dtpDateOut.Value.AddDays(nudDaysBack.Value).ToShortDateString
