Conditional format one cell based on another

Hi and welcome to the forum

You do this with Conditional Formatting. Assuming the 2 values are in A1 and A2 (adjust the following formula as necessary)...

1. highlight the range you want to apply the conditional formatting to (C9)
2. on the home tab, styles, select CF
3. select new rule, select use formula
4. enter =and(C3<A1,C3>A2) format fill as required.

If this isnt what you need, 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.

Happy to help and glad you got it sorted out
