Hi, I'm making a menu in my form, wherein it has FILE, TRANSACTION and REPORT. Under FILE it has BACK, and LOGOUT. In my back menu item, i want to go back to the previous block or previous module. I used previous_block but it's not working in some of my blocks.

Have you read the form builder help topic on previous_block?
That tells you exactly what it does.

Do you have the "previous navigation data block" property set on any of the blocks?

:global.last_block := :system.current_block; 
END;

That code won't compile. Not sure what you are trying to do with it.
