POST changes to the database. When selecting ID value, check whether the same ID already exists and add 1 to previously stored quantity value.

That's what I meant - post changes you made in your form to the database. POST command works well in Forms.

As of code you need to write, I'm afraid you'll have to do that part yourself. If you can't make it work, please, come back here and post what you did. Someone will assist.
