如何在同一页面上运行2个类似的Javascript函数

I have a page that is split into sections and 2 of the sections show images. At first I wanted to show a static image in one section and a rotating image in the other which I have done. But I would now like to have both sections running their own set of rating images, so rotator1 would show images 1-6 and rotator 2 would show images 7-12. With some trial and error I can get it so that section 1 shows rotator 1 and then section 2 show rotator 2 and then goes back to section 1 and so forth.I have a page that is split into sections and 2
