Hello, I have an array with names and difficulties of classes. I needed to limit the array so the classes only repeat once. ![Screenshot 2023-10-07 at 10.36.09 AM](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/5/b/5ba87b41933688c81041fda997e4cd505bf72178.png) In the case below, each class should only be placed once, but because of multiple responses, its not. Also wondering, how to pull up array values in different table. Thank you ---

What are you planning on doing with the array. Usually the functionality dictates how the data should be structured. Don’t want to solve for the wrong problem. ---

Hello, I plan on using these values on a detail page for each class. For that I need each array to not repeat and that way I can send it to a different table and then display them. Thank you ---

So both of the elements in each array should contribute to the uniqueness of your solution? So if I have “Advanced Algebra 2 - 3” and “AP Statistics - 3” is it ok? I don’t really understand your use case. Why should they be unique and why is this configured as an array? ---

The arrays only use was to hold the data but that is not working properly either. The idea behind the screenshots was to average values from a google spreadsheet and then associate it to a class. Then using those values to send it to another table with the class pages. The problem is each response is creating another row, so for example, Advanced Algebra 2 is being repeated twice. That makes it a hassle to display and update for each class page. In the end, the goal is to take values from the spreadsheet average them and associate them to a class. Then take it to a different tab. ---

Why does it have to be “taken to a different tab”? So what do you want to be unique here? The class name? And you want the average of some number for each class? ---

The other tab holds the class detail screens. I need the arrays to only contain one class so that there are no repetitions. For example, only having Advanced Algebra 2 display once. ---

But circling back, why are there multiple Advanced Algebra 2 rows from the start? What exactly is that table storing? ---

The table is storing values taken from a spreadsheet connected to a google form. The reason there are repetitions is because its taking the users choice and then combining it with the class difficulty for that choice.c
