# dual\_pricing\_enter\_amount {% columns %} {% column width="33%" %} ![](/files/nnpOLCPdSva0yoeUg035) {% endcolumn %} {% column %} **Description** Merchant is prompted to enter the transaction amount. The amount is validated against configuration to make sure that it is within the allowed maximum. For purchase, 0 amount is not allowed. \ **Merchant action** Selecting *Continue* starts the payment flow. Selecting *Other* prompts the merchant for other transaction options. \ **Configuration Parameters** `Merchant.DualPricingEnabled` - Sets the feature flag to enable the feature. `Merchant.CashEnabled` - Enables Cash handling for the terminal. `Merchant.DualPricingAdjustmentRate` - Adjustment rate represented by a positive or negative decimal number. A negative rate will yield an adjusted/lower CASH price, while a positive rate will yield an adjusted/higher NON-CASH price. The rate is entered as a percentage value, without the % character. Examples: -3.125 (i.e. Negative 3.125%), 2.75 (i.e. 2.75%), 0.625 (i.e. 0.625%). To enable the feature on the terminal, the feature flags `DualPricingEnabled` and `CashEnabled` should be enabled, and the `DualPricingAdjustmentRate` parameter should contain a non-zero number. {% endcolumn %} {% endcolumns %} \--- --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
