ill trying to report an invoice
my app return all the vars to print include INVOICE NUMBER
the Function generates Invoices to N .

How can generate Just one invoice (especifically number) ?
to print

Use the report's SelectionFormula property

VB Code:

Report1.SelectionFormula = "{tablename.Invoice Number} = 12345"
