1. Type in textBox on layout1 ... e.g. "Rob"
click button and store TextBox.Text in variable/dictionary/array/webstorage etc
then send to layout2
Text reads ... set text ... "Hello " & variable
I would recommend, you being completely new to do the beginner games which cover all the basics and more. Also read the manual, but you will get more benefit from actually building the games, not copy paste, but actually building it event by event.

Open C2 click new and scroll down that long list to any example and knock yourself out.
