Need help with a SUM

[Serated]

Hi, Im using Crystal XI and would like to know the following.
If i have parameters {?startdate} and a {?enddate}. I would like to have a sum on the total amount Invoices for a year up to {?enddate}.

Fields

Invoice.TotalGst
Invoice.Invoicedate which the parameters are on

if your parameters included in yor record selction criteria then the only invoices for the year will be returned. So if you add a Grand Total summary (Insert>Grand Total) on the {Invoice.TotalGst} then that should return what you are looking for.
