SSIS Task Won't Execute

Hi,

Attached screen is a partial flow of my SSIS which the Foreach Loop Container is not being executed.  From my first design, I only have the Foreach Loop Container which runs fine without issue.  Due to programming spec changes, I added the Expression Task and process A to run prior to execute the Foreach Loop Container.  Once I did that, SSIS stop at either the completion of the task A on Sunday or it stop before execute the Foreach Loop Container on weekday.  Any idea why it does not execute the Foreach Loop Container?  Did I miss something here?

Thanks,

Brian
