154351 OSC-Make PHP Button into Text

Hi guys, I am running Oscommerce and we just installed wishlist 2.0. They provide a code to put on the [login to view URL] page so that when users click it, the product will be added to there wishlist. The code they provide is a button(image)link and I'd prefer to use a text link but am unable to. I have attached the install code for the wishlist mod. The code I need changed is the last part of step 3. Thanks
