I have 2 custom properties.

ChargedBit (Boolean)  
ChargedTime (String which has a query to display the current time)

Chargedbit is linked to a button.

When ChargedBit goes true i want to send ChargedTime to a tag called Charged Time-Date

I know it needs an if true statement but I cant figure it out and I’ve searched and cant find anything similar.

This Python script needs to go into the propertyChange event of the button. Modify it as needed.

```auto
if event.propertyName == "ChargedBit":
	if event.newValue == True:
		system.tag.write("Charged Time-Date", event.source.ChargedTime)
```

Best,
