Show us the expression. Please see [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831).

You can't use a number for a border. You must use the [toBorder() expression function](https://www.docs.inductiveautomation.com/docs/8.1/appendix/expression-functions/type-casting/toBorder).

What's the tag supposed to do? Can you give me a general description of the conditions, component, and desired border outcome?

Make a custom property and bind the tag to that. Then use that property in the `toBorder()` expression.

Looks like you're trying to coerce `"2"` to a border instead of `2` but also [^](https://forum.inductiveautomation.com/t/cannot-coerce-value-2-into-type-interface-javax-swing-border-border/100330/3)
