First, before anyone beats me to it, any time you are posting code in the forums follow this guide [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831) so it will format nicely and be more readable.

As per your script, the one thing I can see is incorrect is the way you are using `currentValue`. If you look at the parameter definitions on top the `currentValue` and `previousValue` are QualifiedValues which means they can’t be used like an integer for comparison.

What you’d have to do in this case is extract the raw value using `currentValue.value` to compare. This will come up more throughout your experience with Ignition, so I’d recommend familiarizing yourself with the concept ([Scripting Object Reference: QualifiedValue](https://www.docs.inductiveautomation.com/docs/8.1/appendix/reference-pages/scripting-object-reference#qualifiedvalue)).
