My data range is `L1:L26`

, and its values are a mixture of numbers & strings.

`L5`

, `L8`

, `L11`

, `L14`

, `L20`

, `L23`

& `L26`

contain numbers. The rest contain strings.

I'm trying to get the sum of the first 3 numeric values.
These values are 7, 45 & 11, so the result, stored in `M2`

, should be 63.

I'm using the following formula:

```
{=Sum(Sum(Offset(L1, Small(If(ISNUMBER (L2:L26), Row(L2:L26)))))}
```

The formula produces an error.

NB: It's an array formula.
