I need help on this issue.
Some of the products located on the table products have item color and imprint color which are two separate fields in the same table. Other products don't need to have something in these fields so for that products these fields are blank.
When I print an invoice, these fields appears for all products like the picture here
What I want is to display the item color and imprint color ONLY if they are not blank.
How can I do that?
Thank you in advance for your help.
