## **Problem and Background**
The _basket\_value parameter in the_ [Conversion Basket Page View pixel](🔗) denotes the total price of the checkout basket, usually including tax, discounts, shipping, and/or discounts in the account currency. This parameter should use the same order value/transaction total that you report to your analytics partner.
We have a check in place that determines if _basket\_value_ falls within a minimum and maximum range, where the calculation is:
**min\_value** = _calculated\_basket\_value_\* - 20% of _basket\_value_ (here 20% includes the tax and shipping)
**max\_value** = _calculated\_basket\_value_\* + 20% of _basket\_value_ (here 20% includes the tax and shipping)
\*_calculated by summing item\_count and item\_price_
## **Common Causes**
This issue usually occurs if you have high shipping costs and taxes. Additionally, you can get this error if you allow shoppers to apply coupons against the basket total.
We expect this error from time to time. The default threshold is 5%. It's unnecessary to investigate if the error percentage is low, and it's normal for your shipping, tax, and discount orders.
An investigation is needed if the percentage deviates from this normally accepted range.
## **Debugging Steps**
### 1. Checking _basket\_value_ discrepancies
To debug this issue, follow the steps below:
Download the Failure Examples file provided under the Alert Graph.
Compare the basket details sent (in 1) with the acceptable range and actually reported revenue (in 2). In the example below, the Actual revenue shows 0, which is incorrect. This could happen if the _basket\_value_ is not set or if it is set to zero.
### 2. Checking _basket_ parameter issues
You can validate if there’s an issue with the basket parameter. If you’re sending _price\*quantity_ in the price parameter, then the check can fail.
For example, if a shopper buys 2 of an item that is priced at $10 each:
✅ **Correct values sent in basket parameter**:
Price: $10 Quantity: 2
❌ **Incorrect values sent in basket parameter**:
Price: $20 Quantity: 2
