Hello everyone,
I have a repeater module that I would like to repeat depending on the number of values in the array that are not empty (the array length is 10, however the number of values that are not empty can vary from 1-10)
I have tried this formula in a repeater module : {{length(1.Entry-Name != “”)}} however it is outputting length of 4, when based on the input, it should be outputting 2.
Any suggestions on the correct formula for this would be a great help thank you.
The better answer is do not use a repeater module at all.
When there is an ARRAY, think ITERATOR.
Then, you can remove empty strings from an array with the built-in function remove
e.g.:
{{ remove(1.array; emptystring) }}
Output:
For more information, see the function documentation in the Help Center.
Here are some useful links and guides you can use to learn more on how to use the Make platform, apps, and app modules. I found these useful when I was learning Make, and hope they might benefit you too —

Hi @hb ,
Welcome to Make Community!
Please check the below images and notes.
Input Array:-
Length Function:-
Output :-
{{length(remove(1.array; emptystring))}}
Please use this function in the repeater to get the length of a non-empty array.
