displaying and updating records in a form

Hello, Not sure if this went out, apologies if this is a double post. I'm having difficulty tying something together. I'm wanting to display a record from a database in a form, information from the various fields in the database goes in to their coresponding fields in the form, for example address field of the database goes in to the address field of the form etc. If I then edit and resubmit that same form the field or fields edited and only them will be updated. I'd like this to be all in one file. This tells me I need three queries, one a method to display records for selection and editing which I have, the second to select the specific record based on the ID in this case and to put that in the form which isn't working the form display part, and the third to update any altered fields which I don't have. If anyone has code like this i'd appreciate it. Thanks. Dave.
