Hello thunkers. Today im here for the following issue: I will simplify things to focus only on result, so lets say ill generate 2 lists, as in image below. After generating, because were generated in the same time, i will know exactly that the 3rd value in list1 will be “1,3” , and the same 3rd v…

https://x.thunkable.com/projectPage/60d78e2a5e21e600110b78b4 Check this. Remove the shuffle block and use app variable myList to see sorted list. I made it just in case you ask.

Fortunatly, list1 and list2 are properties of the same object (as you see in block2) So if i sort list1, list2 will have the same order based on list 1 ? this simplify things alot… Thank you very much

Yes, when they are in an object they will have the same sorting.

But how do i retrieve “#” - index of list1`s value to apply in my example for list2 ? (that will be the same, as you said … Maybe ill need a new variable to store as a loop this ? later edit: … something like this… [screen] … ill test it as soon as ill get home… Thank you again Latwer, after …

It should be structured this way [image]

Thank you for your time @muneer , but i still didnt get it :frowning: Trying to follow your ideea, i made a simple example: [screen] expecting that on start, ill get as result B, D, A, C. I got instead Error :slight_smile: Thats because INDEX gets value from list, and not value`s index from li…

oh, got it now… need to rethink the whole variables for that. thank you. the problem is that i do not know the lenght of lists, so i need to generate this new object dinamically, but this will do it :slight_smile:

To make it clearer, I added a List Viewer and a button in the screen and following is the code in the click event of the button. Every time you click the list will be randomly shuffled but you can see from the list that they relation between the numbers and letters remain unchanged. [image]

“shuffle” is the easy thing… but i need it to be sorted by value1 in your examples :frowning: … and dunno how to… and im returning at the beginning of the problem…

need to study further to understand all of those… JSON …mmm … thank you very much for your time… and finally got the right answer… JSON was the key and with your help i learned something new… thank you [screen]
