Using a variable in coded date - vba

Question

I am trying to pull all data entries that are within a userform selected month and year. I can get the code to run fine when I hard code the year but I want the year to come off of a text box. I converted the Textbox value to an integer using Cint() and dim'd it to "Year" in my if statement. I can get it to work if I write Cdate("3/1/2016"), but I want see if there is a way to run it like: Cdate("3/1/Year"). I tried it this way and get a typematch error on the Cdate Im pretty new to VBA so excuse my stupidity.
Ignore the "Month" variable I was just using that to put a stop on the code and step it through to see if it would enter my if statement.
Thanks in advance.
My Code
Private Sub OKBtn_Click()
Dim Sales As Range
Dim Year As Integer
Dim Month As Integer
Dim i As Integer
Year = CInt(YearText.Value)
Set Sales = Worksheets("Sales").Range("A4")
i = 0
If Sales.Offset(i, 1).Value >= CDate("3/1/2016") And Sales.Offset(i, 1).Value <= CDate(" 3/31/2016 ") Then
Month = 1
End If

In order for the CDate to work, you need to seperate the stings inside the brackets to 2 parts
1.The constant, in your case "3/1/".
2.And the variable, CInt(YearText.Value).
Option Explicit
Private Sub OKBtn_Click()
Dim DDate As Date
DDate = CDate("3/1/" & CInt(YearText.Value))
' for debug only
MsgBox "Date entered is :" & DDate
End Sub
