Gary,
Thanks for the investigation. Unfortunately, im on a bit of a timetable and had to move on. I used a frmDataForm instead, because it works for me there. It's not the proper form choice, but its the only one I could get to work. I have no idea why I cant get mine to work on frmDataChild. Would you send me the code you used to populate the mover, or the actual form itself. Maybe that will give me some insight on the problem.

I used the following:
LOCAL lcJob
lcJobNum=inspparams.jobnum
************ get list
Dimension aList(1), aPicked(1)
select alltrim(inspparams.feature);
from ('inspparams');
WHERE inspparams.jobnum=(lcJobNum);
into array aList
thisform.mymover.setvalue(@aList,@aPicked)
**************************************************************

perhaps it has something to do with the select statement. But it works on the frmDataForm "for me"

Thanks again, steve
By the way, when I used the debugger, it just locked up again. It pointed me to some code higher up in the heirarchy of the error handler for codemine.
