Salve a tutta la comunità, sono alle prime armi con app inventor 2
Volevo provare una semplice operazione matematica, ho creato 3 caselle di testo che ho settato solo per inserire numeri, nella prima casella inserisco un importo in euro esempio 1500,00 ( i decimali in automatico ) nel secondo un altro importo 1200,00 la terza casella mi deve dare la sottrazione una volta che i due campi sono pieni.
Mi spiegate come fare?
The numbers go into the .Text values of the text boxes.
Assign the answer into the .Text value of your label.
Do the work in a Button1.Click event.

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles
