Hopefully someone can help here.

I have a Small workflow that sets the status of an item to "Inactive".

I'm trying to get a site workflow running that will see that "inactive" status, calculate a date (based on an existing column...add 3 days to that date - in the other column) then update the item with the newly calculated date in a "date" field.

I've tried all kinds of ways to calculate and update including variables but the workflow just STOPS at that updating part. Can anyone help me out here.
