I’ve got a bunch of dropdown views in a flex repeater. Each option has a db query binding.

 ![Perspective flex repeater dropdowns](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/7/e7f533a7f3f4ba98af4631766b46b8117d41cbe1.png)

I want to refresh them on receipt of a message so I’m using this script.

```auto
	for inst in self.props.instances:
		system.perspective.print(inst.caption) # Prints the dropdown label.
		system.perspective.print(inst) # Print the binding object.
		inst.refreshBinding("ddOptions") # Update the dropdown param binding.

```

It prints the label caption and the binding object for the first dropdown view but doesn’t do the rest of them.

What have I missed?

`refreshBinding` is a _Component_-scoped function, not a property-scoped function. So you would use it like so:

```auto
for x in range(len(self.props.instances)):
    self.refreshBinding('props.instances[{0}].ddOptions'.format(x))

```

where `self` is a reference to the component while in a Message Handler.

That works, thanks! I’m not familiar with that syntax so I’ll have to study it.

Was that a quick midnight forum check before you get some sleep? I’m in Ireland so you got my day off to a good start.

The syntax boils down to obtaining a Perspective component to act on, and then providing the path of the binding to refresh. If you need to update a binding on a different component, you can do that as well:

```auto
self.getSibling('SiblingTable').refreshBinding('props.data')

```
