New widget area is swapping the sidebar

Hey,
First of all, sorry for my bad english. I build an website with atahualpa and finally I created a new widget area. I put the code in "Content above the loop".

Code:
<?php
if(is_front_page())
{
?>
<?php bfa_widget_area('name=My widget area&cells=4&align=1&align_2=9&align_3=7&width_4=7 00&before_widget=<div id="%1$s" class="header-widget %2$s">&after_widget=</div>'); ?>
<?php
}
?>

All works fine, but when I'm going to scale the browser down, the new widget in the new widget area is swapping the sidebar. I attach a foto where you can see exactly what I mean.

Thank you!!
