How to validate comment section in shipping?

[rookiecoder]

The customer must fill in the comment section before they proceed to payment section. Any tips where should I go? Thanks.

Try Order Attributes extension. You can set required fields for order.

Is there other way? For example by alteration of certain codes in public_html directory? changes should be done where?

Thanks for your answer.

Hello.
This is because you have only one shipping method and AbanteCart skip shipping method selection page. In case you have several shipping methods available customers fill comment before payment section
