concurrent program date parameter is not showing current date

Hi all I am trying to schedule a concurrent program based on current date using a date parameter in default type and default value, I have tried using Current Date from default type and I have tried using sql statement and placing Select sysdate from dual in default type. I have scheduled this concurrent program to run every day at a certain time however when it runs, the parameter date never changes, it has the same date as first day of run. What am I doing wrong.
