retrieve data from dataset and use them in the code

This screenshots do not really help.
Try to debug it by your own.
You told in your last post that you get the following results…

I get the following object, how can i retrieve one of the above field?
cleanJerk: 130
weight: 76
benchPress: 100
email: “d.zibra@yahoo.it”
_id: “10544d32-f484-47f0-aa55-1fe052227744”
_owner: “10544d32-f484-47f0-aa55-1fe052227744”

You now should take a look onto the structure of this object in the console (use the console of Google-Chrome.)

Once you have the results in front of your eyes, take a look how it is structured.

When this here did not work for you…

let weight = result.items.weight; console.log(weight)
letID= result.items._id; console.log(ID)
letOWNER= result.items._owner;console.log(OWNER)
letEMAIL= result.items.email; console.log()

Perhaps this one will work…

let weight = result.items[0].weight; console.log(weight)
let ID= result.items[0]._id; console.log(ID)
let OWNER= result.items[0]._owner; console.log(OWNER)
let EMAIL= result.items[0].email; console.log(EMAIL)
