Conditional formatting to highlight cell that matches same cell in different sheet

Hello all,

Here is my challenge: I have a spreadsheet made up of 5 different sheets. Four of these sheets represent a different company (Company A, B, C, & D) and show their prices for a range of products at a range of quantities. I then have 1 sheet called “LOWEST PRICE” that pulls whatever price is lowest from Company A, B, C, or D.

The problem is that on the “LOWEST PRICE” sheet I have no way of determining which company that price is being pulled from. I would like to use conditional formatting to highlight each price so that I know which company it is coming from.

Here is a link to a simplified version of the spreadsheet so you can see what I am talking about:

I realize I could just check manually, but my finalized spreadsheet is going to be a lot more complex and I am hoping I can get this conditional formatting to work. I have been able to get it to work for Company A, but not for the rest of the companies.

Any help is greatly appreciated!

Cheers
