Hello. I am currently developing a Rock Paper Scissors App for my AP Class. However, when I attempt to check one of my boxes, the app becomes unresponsive and a white Screen appears as it crashes. Can anyone help me resolve this issue? This is the final hurdle to completing my project. Here's my .aia file. I could try to include a screen recording if that helps.

Hello. I have some code written for my app, and it looks perfect, but my companion app keeps crashing due to my while test do loop. Anyway to fix this?
please explain why you need a infinite while loop? what do you want to do?
I want to allow the player to keep a win streak going. I thought that using an infinite loop would be able to keep the procedure running in the background while the player went against the bot. I put breaks when the player would lose/ruin his streak, in efforts to keep my app from crashing, but that has been unsuccessful.
a global variable will be ok to record the wins. no need a infinite loop.
The only thing about a global variable is, I need both a parameter and loop in order to receive full credit for my project. Do you have any suggestions for implementing a parameter? I'm kind of at a loss as to how to implement one.
sorry, not understand this.
I'm working on this project for school. My teacher is unable to help me due to AP regulations, that is why I'm coming to this forum for help.
The idea of a win streak requires an extra global variable, to track the number of CONSECUTIVE wins. Such a variable would need to be reset to 0 after each loss.
It's like one of those factory signs, N Days Since Last Accident.
There is no looping involved for that, just diligent logic when a win or loss occurs.
Okay, so how would you suggest I implement a loop and parameter into the project?
Please post the complete project description of your school project including its requirements so we can better understand and be able to help

To loop, you need a data structure to loop over, for example doing a table lookup.
This just like a jogger, who needs a jogging path to run. Standing in place and stomping your feet doesn't count.
Imagine you had a table of RPS rules, with three columns:
Since there are three times 3 = 9 combinations, there would be 9 rows in that table.
That table has the rules for playing RPS, for example some of the rows would read
rock,paper,2 because paper covers rock, and
paper,rock,1 for the opposite combination, and
rock,rock,0 because rock vs rock is a draw.
So imagine a procedure that received 2 parameters for the player choices, and returns 0,1,2 based on its table lookup.
The loop would be in the procedure, as it goes through indexes 1-9 and compares columns 1,2 against the 2 parameters to see which row matches the input. Return value would be 0,1,2 based on the lookup.
That gives you a loop and parameters.
(Advanced list blocks could do it in one block, but you have to learn to walk before you learn to run.)
P.S. A table based solution also has the advantage of extensibility. For example, you could add a 4th option ("lemon meringue pie") just by adding extra rows to the table. (In addition to an extra Button and picture.) I leave it to you to figure out how to play the Lemon Meringue Pie choice.
Procedure with Parameter
^ This procedure must include a loop, selection (if/then), and sequencing
List
Calls to the procedure.
Thank you so much for this approach. I have a multiplayer setting in my app, and I'm thinking I can use this example to implement a more refined program when it comes to defining a winner between player 1 and 2. I'll update you as I code. <3
Could you provide an example as to how you would code a table lookup? You don't have to program anything, but I'd appreciate if you sent a YouTube link or referred to another forum.
Take note of a common recipe for building these procedures, I call it the value procedure sandwich because it always has three layers:
