execute package task

I am missing something simple that's killing me.

I am trying to execute a child ssis package using the execute package task. I add execute package task to the parent package and in the package task editor, under the package options I choose: filesystem for location, I choose new connection and create a connection to the package on the filesystem I want to execute, packagenamereadonly is blank. I execute the parent package and get an error that I did not specify the name of the package in the execute package task object. Now, since I can't populate the package name, as that option is readonly, I am not sure how to remove my headache. Anyone see what I'm doing wrong? None of these packages have security.

Ok, nevermind.

The error was actually in my child package. The child SSIS package was running a DTS 2000 package via the execute DTS2000 package task. The DTS 2000 package was loaded internally and for some reason there was a corruption somewhere in that task. When I deleted the task and reloaded the DTS 2000 package the problem was resolved.
