Perspective is completely different than Vision. If you want a selectedStringValue for your dropdown, you will have to create one. Fortunately, it's not that difficult to do.  
• First, add a custom property to your dropdown called selectedStringValue:

• Then, click the binding icon next to the custom property

• Bind the selectedStringValue custom property to the value property of the dropdown:

• Before closing the Edit Binding Dialog Box, click the Add Transform button and select Script:

• Add the following script, and **click Apply** before closing the Edit Binding Dialog Box:

```auto
#def transform(self, value, quality, timestamp):
	selectedStringValue = ''
	for index in range(len(self.props.options)):
		if self.props.options[index].value == value:
			selectedStringValue = str(self.props.options[index].label)
			break
	return selectedStringValue

```

The script will loop through the options and return the corresponding selected string value property that can be used in other scripting.

Just remember to give each of your options a unique value:
