Dynamic maxItems in Repeater function

Get Help
1

Hi everyone,
I’m using the repeater beta code. It works well.
But I would like to change that maxItems parameter dynamically.
I want the user to enter the number of members in an already-created field.
Then I want to get this variable & put it in my repeater function.
I tried to get that value with get_field_value but it crashes.
Thanks for the help !

Can you share your code William?
