Using Date to Filter Entries I am trying to pull entries that match a date criteria. Any ideas why this is not working?

{% set entries = craft.entries({
section: 'leads',
lastAssigned: '("now"|date_modify("-3 days"))'
}) %}


I get the following error.

Fatal error: Call to a member function getTimestamp() on a non-object in .../craft/app/helpers/DbHelper.php on line 597
I believe it's the quotes that is throwing it off. Try this:

{% set entries = craft.entries({
section: 'leads',
lastAssigned: now | date_modify("-3 days")
}) %}
