We are on Enterprise Version 6.3 12-03-13

We are trying to setup a form that prints a nominal transaction and that includes the invalidated red lines through the relevant lines when an update mark is performed. We want the redlines to print out but we can’t get this to happen.
Can you tell us how to get the invalidated red lines to print on a form layout please? Is it some field argument that we don’t know of or a specific type of font?

Thanks
