Using a different date field causes a fatal error.

When using the `created` field, this module works fine.
But we have content that has a "Source Publish Date" field that's different from the "created" field.

"source_publish_date" is a date field.

When I try to use this as the `Date Field Name` in the Format Settings.

I just get a nice big error message.

I'm trying to use the same Date format as created is (html_date), but... Still getting this.

Is there a required date format?

Thoughts?

Thank you!
