Lets say I have a string "COLIN". 

The numeric value of this string would is worth:

> 
> 3 + 15 + 12 + 9 + 14 = 53. 
> 
> 
> 

So

> 
> A = 1, B = 2, C = 3, and so on. 
> 
>

I have no idea how to even start in F# for this.

```
let mutable nametotal = 0
let rec tcalculate name =
    name.ToString().ToCharArray()
    |> Seq.length

```

Here is what I have so far. The `seq.length` is just there for testing to see if the `toCharArray` actually worked.
