Hey Chuck, for lack of a better set of words: how do you do what you just described?

I'm trying to automate the process of making a quiz essentially, and i've gotten everything sorted aside from the fact that the questions being all of differing lengths means the text doesn't always fit wholly into any given space. I've gotten so far as to making it fit within the side constraints of the text box but when there's too much text it just stays the same size and cuts off any excess text.

I'm fairly unfamiliar with scripting and am starting to look into it but if you could let me know how exactly you do what you described in the above response that would be amazing and would complete the last step of an automation process that would save me literal hours each week. 

Much appreciated if you can explain 🙂

Hi Nancy,

Thank you for the answer, I would just like to clarify my intention.

Let's say for instance I create a "text box" and in this text box I make the words "Hello World" fit perfectly with 36 pt. Use it as a template for the next one and write "Hello World, it's Monday". Is it not possible to set it so that it can shrink the font automatically so that it stays:

1. On the same line, shrinking the font to accommodate (not that important)

Or

2. Shrink the font to remain within the width and height of the box?

Does your comment still apply, or is there a way?
