View source for Why are the "Net amount", "VAT amount" and "Total amount" fields marked red?

After the recognition process, fields can be colored in different background colors:
* '''Yellow''': there are different possibilities available. The most probable value is proposed. When selecting the field, all possible values are proposed.
<br/>{{warning|When a yellow field is available, you always need to confirm the value. A document will not be entirely valid when there are yellow fields available. Press ''"Enter"'' or ''"Tab"'' on your keyboard to confirm a value.}}<br/>
* '''Red''': this field is required, but no value could be found in the recognition process or the validation check performed on that field did not succeed.
<br/>{{warning|Invoices with red or yellow fields can't be booked into the accountancy package.}}
