Interactive PDF - Linked textboxes, resize font

Hello,

I am creating an interactive pdf file. I have linked several textboxes so that on a last page a summary is created with all the data entered. I linked the textboxes by giving them the same name. The fields are smaller on the last page than on the fill-in pages, because you need to be able to read the whole overview at a glance. How can I if there is more text than fits in the field, reduce the font size automatically, or make the text field scrollable?
