Yeah  In some other field when i define ENT(@*) i get error message but when i do it on ID of usysidx.frm I cant get it not sure why it works on other sceens and not on usysidx.frm

AFAIK, usysidx.frm is a uniface internal component (delivered in .../common/usys You may get all kind of these problems when messing around with these internals.
