Changing a link

Awhile ago I had bought a template and had someone else install for me and I just realized one of the links in the header is incorrect. Currently the link is pointing to a direct post and I need it to link to a page instead.

Anyone know where I can change the link?

Link currently goes to here:

http://ifyougiveagirlaring.com/2012/03/08/lilly-pulitzer-giveaway-at-just-another-preppy-shopaholic/

AND I need it to go here:
