@Al_Chen, the display column sets the display value of the row but does not affect the underlying type of the row reference value. Think of it a bit like an envelope tuple with values `(tableId, rowId, displayValue)`.

In your example, since the displayValue is a people reference, a typical `Summary` row’s `thisRow` value would be something like:

```auto
(tableId = summaryTable, rowId = xyz, displayValue = @Al_Chen)

```

So if you take a formula such as `[Detailed Costs].Filter(Name = thisRow).Cost.Sum()` it’s going to be comparing `Name = thisRow` which translates to:

```auto
@Al_Chen === (tableId = summaryTable, rowId = xyz, displayValue = @Al_Chen)
→ #fail

```

which will never match. If on the other hand you use `thisRow.People` you’ll be comparing:

```auto
@Al_Chen === (tableId = summaryTable, rowId = xyz, displayValue = @Al_Chen)-->People
→ @Al_Chen === @Al_Chen
→ success!

```
