VBA Code is not Entering UserForm Values on Worksheet

Thank you nathansav for your help. I've fixed my code per your advice, and now I am receiving this error:

Application-defined or object-defined error

Did I forget to define something?

Here is my updated code:

Private Sub btnOkay_Click()
Dim LastRow As Long

'Adds 1 to get to the Row following the last populated Row
LastRow = Worksheets("2014").Cells(Rows.Count, 1).End(xlUp).Offset(1)
Worksheets("2014").Range("D" & LastRow).Value = tbNetSales.Value
Worksheets("2014").Range("G" & LastRow).Value = tbDiscounts.Value
Worksheets("2014").Range("P" & LastRow).Value = tbCreditCards.Value

End Sub
