I have a basic script to switch border color given an integer value change. I’d like to add a feature where if a certain event occurs in the system, I can make the border color blink. This would need to occur only while the variable is equal to 1 and the event occurs. Script would otherwise remain normal where values = solid colors.

```python
toBorder(
  "line;" +
  switch(
    {[default]PLC/INTERNAL/OVERVIEW/STARTUP TREE/INIT_STARTUP ROUGHING PRESSURE},
    0, 1, 2, 3,
    "0,0,0,255", // black
    "255,153,0,255", // yellow
    "0,204,51,255", // green
    "255,0,0,255", // red
    "0,0,0,255" // fallback: black
  ) +
  ";2"
)

```

Use a custom property and custom styles. Much easier and it will animate.

More info on the style customizer (absolutely the way to go here):
