How did you generate the count list file?
The Sku list file contains Sku, UPC, description, Price, etc. It is used by the scanner.
The count list is output from the scanner. It should be a comma delimited CSV file which contains Sku(or barcode or UPC), Quantity. It should not include the header (column names). It looks like this:
SKU_70-RED-SMALL,1
SKU_37,2
08621611811,3
