## Explanation

This formula uses structured references to feed table ranges into the SUMIFS function.

The sum range is provided as **Table1[Total]**, the criteria range is provided as **Table1[Item]**, and criteria comes from values in column I.

The formula in I5 is:

```
=SUMIFS(Table1[Total],Table1[Item],H5)
```

which resolves to:

```
=SUMIFS(F5:F89,D5:D89,"Shorts")
```

The SUMIFS function returns 288, the sum values in the Total column where the value in the Item column is "Shorts".
