Forms :: Append Data To A Table Entered By User

How I would go about appending data to a table that has been entered by a user on a form.

My initial idea to tackle this was to create a number of text boxes as a method of user input which would all then transfer to a table but this doesn't have much longevity to it(if the database requires additional columns to be added, etc.)

The setup at the moment is two tables, a main table, and a temporary table(which is where I intend to first store the user input, this is so that the user can view what they have entered and make any necessary changes(undo))

I'm wondering if there are any easier ways to go about this such as, a msgbox appears and asks the user to enter each individual column data for a row. This doesn't sound like the most efficient way but efficiency isn't a priority right now and is something I'll look at later.

I'd like it so that a user can input data into a number of text boxes, a button has an onclick event that will append all entered values to the temporary table, this is then relayed(I'm assuming through requery?) back to the user as a way of checking before really adding it to the main database, and then if they're happy there is another button which is then enabled so they can add it to the main database.
