Searching For Mistakes In Document While Using Another Document As Reference

I am processing a fair few Invoices, which are being sent to me via e-mail as excel documents, very often they contain mistakes, a decent amount of mistakes. Usually the prices are wrong.

I keep track of every single entry on the invoice on my own document - Tracker, which I consider to be the superior/more correct document to the Invoice presented to me by my contractor.

Both of the documents have a reference number, which is a specific docket number, and horizontally, in the invoice, there is going to be a price for this docket. In my document, there is going to be a separate column for the total price.

Is it possible (I guess with VBA) to check for mistakes in the Invoice, but use the Tracker as a reference for this check.

Tracker has
columns
A - Name
B - Department
C - Date
D - Docket No.
C - Total price for the docket (calculation of E to Z)
E to Z - all smaller entries

Invoice has
columns
A - Date
B - Docket No.
C to E price for that docket, but it is spread, because departments are separated out, so each VAT account can be charged accordingly. I guess it is possible to do a separate column for the price, if it is easier to do a script that way.

Basically, I need to check if in the Invoice document, the price (C to E) for Docket No. (B) is the same as the price (C) for the Docket No. (D) in the Tracker.

I would like the wrong entries to be highlighted on the Invoice Document, so I can see straight away, that this needs attention.

Not always the price is wrong, sometimes the Docket No. is spelled incorrectly (Dyslexic contractor), hence the highlighting.
