hello all, I am doing an app that is doing scan of EAN and I have a strange behavior on list. ![Capture d’écran 2022-10-06 à 05.21.08](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/f/a/fa8773b33b852343821aea5365782c6e366fb4f2.png) the text2 gives me 1 but the text3 gives me 0 do you have any ideas ? maybe I am too tired to see something obvious ☹ thanks for your help. ---

No, that doesn’t make much sense. Are you setting the counter variable to zero before each loop starts? You should do that each time you call the barcode scanner. ---

yes I am doing it. I just wonder if it is not a problem of size list. the list is 2442 items. ---

Add another counter variable with a different name. Change it by 1 each time the loop runs (so put the `change` block below the inner `if` block). Display that new counter variable in a label. Then you can see if it’s getting through all 2442 items. ---

with the for each loop it is sure I am going through all items of the list I just made some tests with the component get an item in a list based on the index and there is no issue. the thing that I do not understand is why the component in list find do not find the item ☹ ---

found it 🥳 the value for the scan is not a number but a string. I forced it to a number and it is working ---
