Hello. I'm having a problem updating or deleting certain records in a flat file. Right now, I present an HTML form that displays all the records(lines) in my flat file. Next to each line I have a radio button which holds a unique number as its value. In my flat file, records have a record number at the end of it. When a radio button is selected and either an edit or delete button is pressed, how can I edit, delete the corresponding record in my file?
