Insert Into Syntax Error

Hi

This may be a very silly question but I have the following code which is meant to take data from textboxes, checkboxes etc and insert it into a new record on a table using the INSERT INTO statment. However I am getting a Syntax error in my INSERT INTO statement which i cannot figure out.

Please Help!!?

Private Sub cmdSaveRecord_Click()

Dim SQL As String
Dim Today As String
Dim Ref As String
Dim HK As String
Dim Site As String
Dim Equip As String
Dim Serial As String
Dim Invoice As String
Dim Client As String
Dim HKRef As String
Dim Tested As String
Dim Completed As String
Dim chkHKr As String
Dim Repaired As String
Dim Spares As String
Dim CompDate As String
Dim Exp As String

Today = txtDate
Ref = txtRef
HK = txtHK
Site = txtSite
Equip = txtEquipment
Serial = txtSerial
Invoice = txtInvoice
If cboClient.Column(0) <> Null Then Client = cboClient.Column(0) Else Client = ""
HKRef = txtHKRef
Tested = chkTested.Value
Completed = chkCompleted.Value
chkHKr = chkHK.Value
Repaired = chkRepaired.Value
Spares = chkSpares.Value
CompDate = cldComp.Value
Exp = cldExp.Value


SQL = "INSERT INTO ServiceReport (Date, CallReferenceNo, HongKongFaultNo, Client, Site, Equipment, SerialNo, Tested, Repaired, Spares, HK, ExpectedDate, Completed, InvoiceNo, CompletedDate VALUES (Today, Ref, HK, Site, Equip, Serial, Invoice, Client, HKRef, Tested, Completed, chkHKr, Repaired, Spares, CompDate, Exp)"
