Let's say this is the section you designed and want to move...
1. Click on the section. You'll see a menu come up at the top of it.
2. Click on MOVE.
3. Choose to move "To Another Page"
4. Select the page you want to move it to.
5. Once it's moved to that page, do the same thing, but this time choose Move > On This Page and then use the arrows to move it where you want it.
