# Arena: File name expression

Asked by jeffZA on 2025-09-29

Hello team,
I am using an expression to rename images. It works with Arena Mobile 2, but on the website (2.1.56), the record gets stuck in an infinite loop (a blue circle appears next to the survey name).
Sorry to have to report this!
Jeff
