Incorrectly Formatted CSV File

An error like this when you upload a CSV file means you do not have the correct amount of columns:
Notice: Undefined offset: 16 in /app/code/local/Auctionmaid/Productmatrix/Model/Mysql4/Carrier/Productmatrix.php on line 891
Please read documentation specific to your extension and see extension specific examples to see the amount of columns.
If you are receiving other SQL errors or seeing $0 rates on frontend then please look at you csv configuration for extension closely. We strongly recommend if you see issues you follow these steps to resolve:
  1. If just starting with the extension first use an example csv so you can get a feel of how it works
  2. Reduce down the csv to the actual issue seen, so that you are just focused on that
  3. Reduce any price, weight, country filters on the problem row so that the shipping is easier to achieve
  4. Add back in complexity a bit at a time, testing on each until you are comfortable with how it is working
