Hi guys, Still new to some of this. I'm having issues when using a for loop to drive the creation of instances for a template. The code is creating the correct amount of instances and in the side panel under the instances section, I see all of the data I'm needing to supply my template with, but it's erroring and maybe it's just me being a noob, not sure. The code is below ```python base_URL = system.tag.readBlocking('[default]RestfulEndpointBaseURL')[0].value endpoint_URL = base_URL + self.parent.getChild("HeaderContainer").getChild("MachineName").props.text result = system.net.httpClient().get(endpoint_URL) isCurrentHour = '' if result.statusCode == 200: print result.json views = [] for metric in result.json["content"]["metrics"]: for obj in metric["HourlyKPI"]: views.append({ "currentHour":isCurrentHour, "DT":obj["kpi"]["downtime"], "Hour":obj["hour"], "OEE":obj["kpi"]["oee"], "PT":obj["kpi"]["plannedDt"], "RT":obj["kpi"]["runTime"], "RU":obj["kpi"]["rejects"], "UL":obj["kpi"]["u.lost"], "UP":obj["kpi"]["u.prod"], "UT":obj["kpi"]["u.theorical"]}) return views ``` ![nestedviewerror](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/d/7dee9daec17bc050a37dca009dd0c09fb42bf1ce.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/a/fab1e151ab799947b4938a02437493674cdf5b55.png) ---

I haven't quite figured out how it's supposed to work, but is your last line, `return views`, indented one too many? ---

I tried moving it but it seems to just give me the same amount of instances and the same error regardless of where I put the indent. ---

Are you certain that you're not referencing the same view you're currently in with 'props.path'? ---

Post the (nicely formatted) result.json so we can replicate. ---

How could I be referencing it twice if it's not in the code I posted? Is there some other way to accidentally do this? ---

Ujwal is suggesting the possibility that you have selected the wrong view in the `props.path` dropdown. It will list the view you are working on so it won't stop you choosing it and causing recursion. ---

Well... I'll be... 😂 He's right in assuming this. Jokes on me, I have "hourly template" and "hourbyhour" and got them confused. 🤦‍♂️ Now I'm getting another type of error in the view that says ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/d/8de29d01dce91c937a937f3e310a05f8e1e7418b.png) ---

You haven't shown us the sub-view yet. Copy the AY\_Label object and paste it in here. ---

I got it. I had double {} around my tag within the binding of the background color property. Man copying and pasting from other projects sure throws you into a whirl. Sorry guys. Hope this was a fun thread to tackle this morning 🙃 ---

Good work. Don't forget to check that `return views` indentation. ---

Appreciate you guys! Thank you so much. It's the little things.
