How can i create crystal report from multiple tables that are related.? I need to create a report based on the value provided through selectionformula in visual studio 2005.

Tables are :-

vendor.address
2. Invoice
invoice.id

invoice.amount
invoice.vendorid
inovice.chequenumber
3. Cheque

====================================== =
Vendor details of a selected cheque - Single columns
--------------------------------------------------------------------
Invoices for the same cheque(invoice_number, date, amount) - Multiple columns
---------------------------------------------------------------------
Cheque Details(total amount, date)
