I recall [a version](https://inductiveautomation.canny.io/ignition-features-and-ideas/p/add-expression-function-to-check-if-tag-is-valid-found-and-not-disabled) that was more complicated:

```javascript
indexOf(toStr(qualityOf({tag})), 'Bad_NotFound') = -1 &&
indexOf(toStr(qualityOf({tag})), 'Bad_Disabled') = -1

```

But, as of around 8.1.10:

> Reviving this thread because of changes that landed in the latest nightly build/8.1.10: The gist: In addition to isGood, we've added new expression functions to test each different level (isBad, isUncertain, isError). As a further mechanism to allow direct comparison, e.g. if you want to find out if something is disabled, you can use the new qualityOf expression; this will return the QualityCode object from the input. The equality operator has been 'overloaded' for QualityCodes in expressions…

This [simplified version](https://forum.inductiveautomation.com/t/ignition-extensions-convenience-utilities-for-advanced-users/64615/95) makes everything a **tad** more manageable:

```javascript
qualityOf({tag}) != 'Bad_NotFound' &&
qualityOf({tag}) != 'Bad_Disabled'

```

I am using the above in several views (Edge projects). While it does feel a bit use-case-specific to port over the `isAvailable` function…I’d certainly use it as well. To echo your use, I would be pointing the function at an existing property (which is bound to a tag) as well.
