## Problem and Background
Conversion pixel in which the ‘quantity’ field in the basket is empty or contains a value that is not a number. For example, if a ‘quantity’ field has a value like NaN, undefined or null, etc. then it is considered as not a number.
## Debugging Steps
Request the [Bloomreach Support team](🔗) for the list of all conversion pixels where the ‘quantity’ field in the basket is empty or contains a value that is not a number. Each example gives the order id and basket value from a conversion pixel. Check the quantity of each item in the basket. It will be either 0 or empty or some undefined or null value.
Look up the product id associated with price on your website and product id. If the product is valid then there is an issue with pixel implementation.
## Common Causes
This issue occurs when either the quantity is undefined or 0 for a number of items.
Debug and check the order ids and the baskets that are incorrect and fix it using the Pixel tool.
