Pull Function Will Not Populate Based On Key Field

I have an issue where I need to populate a field in one feature class (Building Permits) with data from another feature class (Building Inspections). The two layers share a key field for permit IDs (one field is lowercase and the other is uppercase). The Building Permit layer has a field called "Electric Amount." I would like to use a pull function in a survey linked to the Building Inspection layer to populate a question with data from the Electric Amount field if the permitids are found to match.

I wrote the following pull function to accomplish this, but the data continually fails to populate in the question even after I used a string conversion to handle the integers that are being pulled into a string field. The function doesn't throw any errors in Connect, but it also doesn't pull in any of the desired data when a form is opened.

string(pulldata("@layer", "ElectricPermit_Amount", "url", "https://services6.arcgis.com/cMgmhwu0L5CeOOoS/arcgis/rest/services/Department_of_Community_Development/FeatureServer/2", "where", "PERMITID='${permitid}'"))

I'm all out of ideas on this one. Can anyone tell me where I might be going wrong?

You don't have the syntax for pulldata correct. This arcticle is super helpful https://community.esri.com/t5/arcgis-survey123-blog/survey123-tricks-of-the-trade-pulldata-quot-layer/ba-p/1224415

and See the formulas page: https://doc.arcgis.com/en/survey123/desktop/create-surveys/xlsformformulas.htm

They have examples further down the page as well. I think you'll need getValue for this one. You're pulldata should look closer to:

pulldata("@layer", "getValue", "attributes.permitId","servicesURL", concat("PERMITID='", ${permitid},"'"))

concat is your friend with this one for the where statement. Also many people find it helpful to have the where statement on a different line then the pulldata function, i'd suggest doing that as well with the string aspect of it. For whatever reason it'll just functions better.

Ugh, you're right. My syntax was all off. I re-worked the function according to your specs and it did end up working.

That Tips & Tricks section for Survey123 was a great resource too. Thanks for all your help!
