Hey @Mark and @User81, I made another type of Asynch loop but this one doesn’t seem to work :
* * *
…Is this part :
In this block from Mark’s tutorial :
essential to make it work ? Thanks !

Yes, you need some `'if'` block controlling the function call there in order to make sure that there is a way to end the loop. Otherwise, you get something called ‘infinite recursion’ .

But If I don’t know how many times I want it to repeat, how should I do ?

I should have looked more closely at your blocks. You do, in fact, have an `'if else'` block that is controlling when to end the recursion/loop. It is the one where you test for `value != "null"`. I suspect, though, that what you really want is just an `'if block'` which calls `'singleuser'` , increments the `'store'` value as you already do and calls `'do somethings'` as you already do. That will loop around as long as `value != "null"` and will stop looping when `value = "null"`.
One thing to note, though, is that I suspect that you want to pass a parameter or two your `singleuser` function, such as `value` and maybe `store`, otherwise it might be difficult for `singleuser` to figure out what to do.

The thing is that the singleuser function is independant and ran only once.
Update : Is this what you were suggesting ?
Thanks for your help ! 🙂

Hey @Mark !
I think you made a small mistake, actually it will loop as long as the value is equal to null 🙂
But can you find why it is not working then ? Because with what you said, all seems to be fine no ? Maybe I am having the same problem as the same time where I have to wait several days for my app to get functionnal by itself ?
Update :
This made it work ! Thanks again for your precious help ! Awesome day ! 🙂
