Oracle Forms

Hello,

I have a 10g master - detail form. I was wondering how can I change background color of text box (NAME) based on non-visivle item (MODIFIED_BY) value.

So far, I have created two visual attributes and have put following code on "WHEN_NEW_BLOCK_INSTANCE" trigger

if( :main.MODIFIED_BY = 'COCO') then

	SET_ITEM_PROPERTY('main.NAME',VISUAL_ATTRIBUTE,'VA_BLUE');
else
	SET_ITEM_PROPERTY('main.NAME',VISUAL_ATTRIBUTE,'VA_RED');
end if;
	

But, it always goes to "ELSE" part and make RED color for all records. Could you please help me with this?

Thanks.
