Hi rayjones9210,
If what you meant is to get a property value of a component in a template within a template repeater, then you can further get the component from the template after you obtain your template from a template receiver.
Something like this:
templateRepeater = event.source.parent.getComponent('Template Repeater') #get the template repeater
templates = templateRepeater.getLoadedTemplates() #get all templates in template repeater
template = templates[0] #note that [0] refers to the first template in the templateRepeater
label = template.getComponent('Label') #get the component in the template
print label.text #get a property value of a component
