Problems Using Temporary Tables

I am declaring a temp table in control flow via Execute SQL task. I then want to use that table as a source in a data task, keep it alive going back to control flow and use it as a destination in another data task following. I am having trouble just getting the first data flow to access that temp table.

In my Execute SQL task, I'm creating a simple temp table. After executing that task, I can head to the data task and change my OLE DB Source to point to that temp table, but I recieve an error about an invalid table name when I attempt to map columns or hit "OK."

Is there something else I need to do to use that temp table as a source or can I only reference it through SQL queries?

Thank you.
