It appears that

:System.Cursor_item = :System.Cursor_block||'.'||Get_Block_property('Head',Last_item)

is never true. Perhaps you might display (using the MESSAGE built-in) left side as well as the result of the right side of the equation sign, compare them and see what is going on.

The code is working perfectly.

Before this coding block i had disabled the lastitem so next_item will not move to the last item. That i removed. Now it is working perfectly.

Anyway thanks little.
