App Inventor - Input an item to a list and then properly display the list
I recently started learning to use App Inventor to create some very primitive apps. I came across this project. Basically, I want to input the item to a list and then use the foreach iteration to properly display the list. However, the results are duplicate. It's as if every time I click the "add" button, the foreach iteration is executed. I spent several hours to search and also think about it, but I cannot figure out a way to solve this problem. Guess I have no talent but luckily I believe in efforts, too.
Here is a screenshot of the blocks and emulator/symptoms. Please let me know if more information is needed. I am a first-time user on stackoverflow and apologize ahead if I'm doing anything wrong. Thank you all in advance!
To explain the screenshot:
First, I enter "a" and hit add button, the list shows as "1.a"; I then enter "b" and hit add button, the list shows as "1.a 2.a 3.b", instead of "1.a 2.b"; finally, I enter "c" and hit add button, the list shows as it is shown in the screenshot...
In your procedure displayList some initialization is missing... just add
set LabelDisplay.Text to "" (empty string) and
set global entreeNum to 0
