I get a lua error when trying to sort on the "Total" column in tab "Sale Rates".

In "Source\DataProviders\SaleRates.lua", the COMPARATORS map is missing a totalPrice entry.
Adding "totalPrice = Auctionator.Utilities.NumberComparator" into the map solves the problem.

Thanks for the bug report. The fix will be in the next normal release and available in the next alpha shortly (once it finishes processing).

A similar problem exists in Posting.lua where "deposit" is missing from the COMPARATORS map

Pushed a fix for that too now 👍
