I’m creating a mathematics application. There are many variables and data, so I would like to set the screen 1 for them. Then the result of the calculation will be shown on screen 2. Please advice and show me for the example.

To get started, put on the screen a little data and make an application with them. Can you draw what should be on screen 1 and screen 2 after the calculations? I have a great thought, but I need to see what you want to do.
Hi actech
This is an example. Actually, there are about 10 data for input on screen 1 and result of 7 equations to show on screen 2.
Some equation also needs the value from the spreadsheet.
On screen 1, you create 10 input fields, 10 global variables of type “app”, a block for receiving data from the SpreadSheet, and a Calculate button.
In the event handler of the Calculate button, you need to assign the values of all 10 input fields to 10 global variables and then go to screen 2 (you can use the Stack type navigator).
When displaying screen 2, you need to make blocks of expressions using global variables that already contain the field values and data from the SpreadSheet. After that, display the result of the calculations on the screen using Labels.
Do you understand this approximate algorithm?
Thank you for your advice.
I don’t know how to use stack type navigator.
Could you please show the example.
For global variables, you means I have to use the first block, the initialize variable to, right?

Yes, assign a block to the initialization block with the initial value. This can be a block with the number 0.
