Input stepper linked to a text box

Hi everyone, I’ve just started on Axure and have no background in coding or any sort of. I am a marketeer who is trying to learn more about UX design.

How do I make actions defined on an input stepper sample form reflect on a different page/text box?

For instance, I am working on an airline prototytipe where user adds into the booking process 2 travellers, 1 luggage etc…how do I make their choices reflect on the initial page once they click apply?

Thank you
