Excel headers with multiple images

I have been trying to create a custom header in an excel worksheet that has my company logo in the left section - some text in the center section - and another logo in the right section.  I insert both logos and they both show {&Picture} in the header creation window, but when I go to my document the logo from the right section is overlaying the logo from the left section in the upper left corner of the page.  How do I get this logo to stay in the right corner??
