I have a table listing various products. There is a form to enter and update those products. I'm having trouble updating the quantity field.
I'm using a split form. I can select a product on the bottom of the form and it fills in all the fields in the top of the form with that products information. I want to add a text box, or something, where I can type in a quantity I received and when I click a button the form will add the received quantity to the previous quantity and update that record.
