SSIS Package not able to loadfromSQLServer in a scripting task

[SQLDeveloper]

I am trying to load and run a ssis package from another ssis package. It works fine when i test it in the VS 2008 while development but when i configue a job to execute the master package it does not invoke the child package.

I am using SQL 2008 R2.

We would need specific detail to be able to offer help. Saying it doesn't work doesn't tell us anything.
