Can anyone help please I've put the code below in the on click event for a button to open my invoice list form and filter it to a date range but when it runs I get syntax error in query in query expression its probably something very stupid but I just cant get it to work. The form is a continuous form based on a group query

Private Sub invoicelistbtn_Click()

Dim StartDate As Date
Dim EndDate As Date
Dim strSQL As String

StartDate = InputBox("Enter Start Date:", "Start Date")
EndDate = InputBox("Enter End Date:", "End Date")

strSQL = "SELECT * FROM InvoiceListQ WHERE InvoiceDate BETWEEN #" & Format(StartDate, "yyyy/mm/dd") & "# AND #" & Format(EndDate, "yyyy/mm/dd") & "#"

DoCmd.OpenForm "InvoiceListF", , , strSQL

End Sub
