Yep that was the root cause... is working now... end up with:

Meant to start a thread not just comment on the snippet

My question is about the ternary; when will it *ever* return `null`?

You effectively have
```
if (A &amp;&amp; B) {
  data[key] = A ? oneThing : null;
}
```
In order to even execute your ternary statement, `A` *has* to be `true`; it will never be anything else, so the ternary will *always* return `oneThing`

`data[key] = results[map[key]] ? results[map[key]][0].value : null;`

Look like I dont understand this entirely I would check to understand it better...

I'm completely guessing, but maybe you wanted `results[map[key]][0] ?` (add the `[0]`)

Evene if I try like this:
`data[key] = results[map[key]].length ? results[map[key]][0].value : results[map[key]];`
Or this:
`data[key] = results[map[key]][0] ? results[map[key]][0].value : results[map[key]];`

I don't get the Booleans

A boolean value stored in `results[map[key]]` will never go through that ternary statement at all because it doesn't have a `length` property, so your `if` will be false and it will go through the `else`

How do you insert code tags into a thread?

```for (var key in map) {
			if (results[map[key]]) {
				data[key] = results[map[key]].length ? results[map[key]][0].value : data[key] = results[map[key]];
			}
		}```

Basically you're iterating over this `map` to pull out the elements themselves *or* for any elements that are Arrays, grab the `value` property from the first element

Yep is working ok now I think this snippet could be use to iterate over any lookupFields result set...

How about
```
for (var key in map) {
  if (util.isArray(results[map[key]])) {
    data[key] = results[map[key]][0].value;
  } else {
    data[key] = results[map[key]];
  }
}
```

Or even more concise
```
for (var key in map) {
  var result = results[map[key]];
  data[key] = util.isArray(result) ? result[0].value : result;
}
```

Good also but ternary does not look nicer? without calling any external anything?

The `N/util` module is always loaded anyway

ohh you can use util the same way you use log? there is more modules like those?

well test it out first and make sure it works before you thank me :slightly_smiling_face:

is working... not using util I think I will stay with the ternary and length version but saving your snippet too..

By the way, do you use anything specific to save snippets like in a central place or something?

Might be a good idea, but I haven't taken the time to set anything like that up

All my code is always in git, so I typically just search my repos
