I’m such case while sending the values from screen one to another screen along with start value also send the screen name… using make a list block… (first item value , second item screen name)

See also Building apps with many screens and SteveJG’s post about advantages/disadvantages, because in only one screen you also can use vertical arrangements to simulate different screens, just set the arrangements to visible = true/false as needed… If you decided to use different screens, then you should switch them correctly, else you will run out of memory after a wh…
