Highlight Cell if Reference is Blank but Display 0

Hi everyone. Would appreciate a little help with my problem.

Please see attached.

Data sheet
- this contains data to use. The cells highlighted in blue are those that have to be filled out. The rest the user should not touch. Sometimes, it is the quantity that has to be filled out, other times it is the rate.

Upload Sheet
- This sheet directly references the data sheet, and if it detects a blank Qty or Rate, it will return a 0. We use this sheet to upload to our accounting system. It does not recognize blanks, so blanks have to be 0.


Problem:
For those cells in the Upload Sheet that references a blank in the Data sheet, I would like them to display a 0 but also be highlighted in RED. The result should look like the Upload Sheet Desired Result sheet. Is there a a way to do this in VBA, or better yet just a simple formula?

Any assistance would be greatly appreciated. Thank you.
