I can’t find the component

Which component can’t you find?

If you are looking for the open another screen with strat value component you can find it in the Control section


I use it with what other components ??

With “get start value”
On screen with text boxes set
Open another screen with start value screenName > Screen2 (or screen you need open)
startValue > Sum of text boxes

Into screen 2 (or you screen)
With screen initizalizate set any variable > get start value

Could you show me this in the blocks visually ??

these are some very basic questions… what about doing some tutorials to learn the basics?

A very good way to learn App Inventor or Kodular is to read the free Inventor’s Manual here in the AI2 free online eBook App Inventor 2 Book: Create Your Own Android Apps … 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 Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps
How to do a lot of basic things with App Inventor are described here: How do you...? .

Also do the tutorials Tutorials for MIT App Inventor to learn the basics of App Inventor, then try something and follow the Top 5 Tips: How to learn App Inventor
