Filtered portal on a home screen

I am having issues creating a filtered portal on a users home screen. I am trying to filter a portal based upon a global number field on the home screen and a calculated number field in the portal record.

I am filtering based upon two fields. The first is my primary field, which displays all records with a status of "Pending" and "In Progress". I have this field set to a check box and can actively filter between the two different statuses. When add the second portal filter and try to filter by specific number, the portal returns no results no matter I set the number to. If instead I set the second filter field to a text field manually type in the value of a record that I know is there, it will display that filtered record.

What am I doing wrong? Can I not filter a portal by a calculated field?
