Ok I got it to work to kinda work, but the link always apears now even when the box is not checked in the add link section of the admin. I think it might be the code I used in links.html to call the tag this is what I have
<%if Mix_And_Match%><a href="<%Mix_And_Match%>">Click Here</a><%endif%>
<%if Mix_And_Match%><a href="<%Mix_And_Match%>">Click Here</a><%endif%>
