15,062,926 | I was wondering how to fix my program which asks for user input on any number.
To terminate the program, you input -99. Everything goes well as far as input goes, until I hit -99 to stop the program where it becomes the minimum. This is my code. The final answer for the minimum value cannot be -99.

1. n = 1
2. 1 == -99 ?
3. n = new input
4. set new minimum from n
5. n == -99?

First (4.) you set the new minimum from `n` (also if `n==-99`), any only then (5.) you test whether it is the value to stop.
I would suggest to change the loop into an infinite loop (`while True`) and then test whether it is -99 (... | You need to check if the number is -99 at the end of the loop.

] | Having looked at the JS file loaded by HotJar i discovered the following code
```
hj.hq.isUndefined(hj.globals.get("userId"))
```
From that i extracted the following
```
hj.globals.get("userId")
```
And this works for me as of today. Hope this helps someone else. Please let me know if it has worked in all cases. | It looks like it is not available in DOM right now.

There are a lot of ways to do it, but almost all will involve using two refs.
This is about as small as I could get it. Depends on what your inputs look like as to whether this would make sense to use.

```none

`0 * ISBLANK(A1:E5)` part is there just to force the desired behavior without modifying (see that multiplication by `0`?) the values you need.
