Hi and welcome to the forum

MY car is making a funny noise, can you make it make a different noise?

lol sorry, but what you asked in your question, is almost the same thing. It is almost impossible to suggest anything without more detail.
i would suggest you upload a sample work book, (all sensitive data removed), showing what data you are working with, a few examples of what your expected outcome is, and how you arrived at that
To attach a file to your post,
click advanced (next to quick post),
scroll down until you see "manage file",
click that and select "add files" (top right corner).
click "select files" find your file, click "open" click "upload" click 'done" bottom right. click "submit reply"

Once the upload is completed the file name will appear below the input boxes in this window.
You can then close the window to return to the new post screen.
