On the html invoice the discount code appears as a link to a popup window. Is there a way of removing this link?

The reason is that when I use the PDFOC, the invoice prints the link to the popup window, and the whole invoice gets pretty messy. I figured that the easiest way to omit this would be to remove the link, as it is pretty unnecessary.

There might be some other solution to fix this that I am not aware of?
