Hi @Tamer_Gezici,

I found a very tricky part of the JS logical judgment.

I used

```auto
if (window.MYTRIALN > 60 || window.MYTRIALN < 60){
    //alert('insideloop');
    continueRoutine = false;
}

```

And put it under Each Frames. The code works.

However, when I switched to

```auto
if (window.MYTRIALN != 60){
    //alert('insideloop');
    continueRoutine = false;
}

```

The code stopped working. Lol

I was also inlighted by [JavaScript - continueRoutine = false -- problem online](https://discourse.psychopy.org/t/javascript-continueroutine-false-problem-online/8669/4)

Therefore, I put it under each frame. Also, I initialized `window.MYTRIALN` as a global variable.

In sum, sort of working. Thank you so much.
