BIDS local window

I am developing a SSIS package using BIDS. I have many variable that are
scope to the Package level. When I set breakpoints and go to the Locals
window, there are no user defined variables only three system variables:
ExecutionDuration, ExecutionStatus, and ExecutionResults. I also added a
Watch window and it list one variable with the Name: Variables, Value: Unable
to evaluate the expression. All the variables the have expressions setting
evaluate with no problems. I am trying to set some variables with an
ExecuteSQL task. Should all variables that are scoped at the Package level
be listed in the Locals window?
