Well, I'm going to have at least 19 instances, 16 of one template, 3 of another.

I couldn't figure out how to go that deep in the example above, so I built another.

This time: Repeater with a dataset, and each instance is a Template of 3 templates.

Each grouping, including the large button is a template, the internal templates/ **UDTs** are the three "line items".

I'm having a hard time wrapping my head around getting to the nested templates/repeaters (in the first post).

```python
repeater = event.source.parent.getComponent('Template Repeater 2')
for template in repeater.loadedTemplates:
	template2 = template.getComponent('Zone_3Pos')
	template2.templateParams['toggle_main'] = 1

```

The _above_ code presents the error: `Nonetype has no attribute: templateParams`, which refers to `template2` variable.

```python
repeater = event.source.parent.getComponent('Template Repeater 2')
for template in repeater.loadedTemplates:
	arguments = []
	for customProp in template.dynamicProps:
		arguments.append(template.getPropertyValue(customProp))
	print(arguments)

```

**EDIT:**  
~~This code prints out 9 values, which appear to be the custom property values of each individual template/ **UDT** and their parent templates. But, I manually counted 10 custom props, instead of 9.~~

_That was wrong... the `customProps` are from the group template, meaning the second nested template._

Print output:

```python
[0, 0, 0, 0
, UDTProperty[type=_types_/Power_Supply_,path=<null>]
, UDTProperty[type=_types_/Power_Supply_,path=<null>]
, UDTProperty[type=_types_/Power_Supply_,path=<null>]
, 7, u'07']

```

Can I assign a value to the parameters from here? If so, how do I target a specific one? Like `template.templateParams['toggle_main'] = 0`?
