i imported the library, so i'm not sure why it doesn't accept what i gave it.

minutes.py
```import datetime
def minutes(datetime_1,datetime_2):
seconds_1 = timedelta.totalseconds(datetime_1)
seconds_2 = timedelta.totalseconds(datetime_2)
return round((seconds_2 - seconds_1) / 60)
```

5 was absolutely arbitrary; sorry for any confusion.

Two options for importing:

Option 1 (recommended): import the entire datetime module requires explicit `datetime.timedelta` below

``` import datetime
def minutes(datetime_1,datetime_2):
seconds_1 = datetime.timedelta.seconds(datetime_1)
...
```

Option 2: from the datetime module, importing only the timedelta class then timedelta on its own will work

```from datetime import timedelta
def minutes(datetime_1,datetime_2):
seconds_1 = timedelta.seconds(datetime_1)
...
```

Either way, `seconds` is a necessary attribute name, and `totalseconds` will not work.

Hi Jason,

I think I found the problem:

```import datetime
seconds_1 = datetime.timedelta(seconds=5)
```

`datetime` is the module that contains the class `timedelta`. `timedelta` receives a parameter named `seconds` (among others)

You can see the docs here.
