Moving main text box in resume template

Hi all -

I'm trying to update my resume using the "Modern Resume" template, but have a slightly annoying issue. I would like to move the main text box (where the body of the resume goes) up on the page. Right now, there is a large blank spot in the middle of the page and I think it looks pretty awful (plus if I could move it up I may fit my resume on one page). But Pages won't let me select the main text box, so I can't move it around. Suggestions?

Thank you in advance.
