Append queries

Hi, Sorry Im quite new to this.

I am trying to create for our company a form where you insert an initial quote to send to a customer and when they agree to it we raise a Sales Invoice.

have a tick box on the Sales Invoice form that will run two append queries to insert the data from tblQuote into tblSalesInvoice and from the subform of details order from tblQuoteDetails to tblSalesInvoiceDetails

The tables (Quote and Quote Details) (SalesInvoice and SalesInvoiceDetails) are linked together by one to many relationships, the problem I have is that when the data is placed into each table from the Quotes tables it doesnt link the tables together via the SalesInvoice primary key. Is there a way to do this?

Any help would be good :rolleyes:

Thanks in advance
