I made an example of a problem I have.
I wrote a code with 2 sections
When I press RUN_1 it calculates X * Y (this is works)
When I press RUN_2 he does not remember the value XY so he does not compute me XYZ (this is not works :( )
Thanks!

You need to keep in mind variable scope. All your callbacks are functions. Variables created inside a function are lost once the function terminates. The way around this in app designer is to create an app property to capture these values. You can then access them using the app.varName syntax.
See here for more.

@Cris LaPierre
Hello again
Unfortunately I could not make it work
What should I call the function?
Is it possible for you to give me an example?
tnx

You are not creating a function. You are creating a propery. There is no need to change the name. Use XY. The only change is, instead of using XY, you would now use app.XY.
You can see an example here: https://www.mathworks.com/help/matlab/creating_guis/share-data-across-callbacks-in-app-designer.html
