Reports between date ranges

[Fie]

hey,


av made a form that allows users to enter date range for a report to be
based on but how do i make it so that i can have a combo box on the
form to that allows users to select employee and data range or have all
employess and enter in a data range?? The code i have for the OK button
just now is



Private Sub cmdOK_Click()
Dim strReport As String 'Name of report to open.
Dim strField As String 'Name of your date field.
Dim strWhere As String 'Where condition for OpenReport.
Const conDateFormat = "\#mm\/dd\/yyyy\#"

strReport = "rptPoints"
strField = "Date"

If IsNull(Me.txtStartDate) Then
If Not IsNull(Me.txtEndDate) Then 'End date, but no start.
strWhere = strField & " <= " & Format(Me.txtEndDate,
conDateFormat)
End If
Else
If IsNull(Me.txtEndDate) Then 'Start date, but no End.
strWhere = strField & " >= " & Format(Me.txtStartDate,
conDateFormat)
Else 'Both start and end dates.
strWhere = strField & " Between " & Format(Me.txtStartDate,
conDateFormat) _
& " And " & Format(Me.txtEndDate, conDateFormat)
End If
End If

' Debug.Print strWhere 'For debugging purposes
only.
DoCmd.OpenReport strReport, acViewPreview, , strWhere
End Sub
