Copying Values from Parent to linked children

Question

We have version Power Scripts 4.8.0.6  I used the example they have online

/*Call this script from a workflow transition post-function.It will set the fields to the value of the matching field in the parent issue.*/ if(isNotNull(parent)) {         summary = %parent%.summary;    description = %parent%.description;    dueDate = %parent%.dueDate;}

However this does not work for me, I keep getting an error (the check fails)

Is there a way you can see what the error is?  I added the post function to the linked Issue...is that correct?

If you run it in console, you need to provide the issue key in the Run Configuration dialog screen:

I can't use the standard Post - Function "Copy Value from other Field because the parameters don't work because the parameters available don't work for our customized Hierarchy,

When I click on Check next to the Check button it says 1 error found but there is no red cross on the line.  There is no detailed message of the error.
