Copy modified files into the right folder

As I am new to Hazel I am having some difficulty understanding how to copy modified files into the right sub-folder. I think I understand the requirement to have a separate rule to go into a folder and then run separate rule(s), but I cannot work out how to write a rule for Hazel to copy files modified in one sub-folder to the equivalent sub-folder.
Setup:
1. Folder A, with
2. Three sub-folders (pdfs, complete and sounds), and
3. if any files modified in sub-folders pdf and sounds, then
4. only the modified files should be copied, to
5. equivalent sub-folders in Folder B.

It is with step 5 that I am having diffculty. Help would be greatly appreciately.
