# Run Dynamic Formula Step

| Step Details |
| --- |
| **Introduced in Version** | 9.17 |
| **Last Modified in Version** | 9.17 |
| **Location** | Designer Entities > Rules |

The **Run Dynamic Formula** Step executes dynamic formulas, supporting customizable result types and error handling, enhancing the flexibility of formula execution workflows. This Step allows Users to pass in a desired formula as text into a Flow without building it in the Formula Designer, enabling faster, high-quality implementation. It also includes options to sanitize input parameter names and ignore arithmetic errors for formulas that contain special characters or null values.

## Properties

#### Formula Settings

| Property | Description | Data Type |
| --- | --- | --- |
| Result Type | Allows Users to select a Result Type for the Dynamic Formula. | Varies |
| Is Array | Allows Users to determine whether the Result Type is an Array. | Boolean |
| Ignore Arithmetic Errors | When set to true, arithmetic operations involving null values return NaN instead of throwing an error. | Boolean |
| Sanitize Input Parameter Name | When set to true, sanitizes input parameter names so formulas containing special characters are parsed correctly and return the expected result. | Boolean |

NoteUse **Sanitize Input Parameter Name** when formula input names contain special characters. Enabling this property helps prevent parsing errors caused by unsupported characters in parameter names.  
Use **Ignore Arithmetic Errors** when formulas may perform arithmetic operations on null values. When enabled, those operations return NaN instead of throwing an error.

#### Inputs

| Property | Description | Data Type |
| --- | --- | --- |
| Formula | Allows Users to select a Formula. | String |
| Inputs | Allows Users to select Inputs for the Formula. | List of DataPair |

#### Outputs

| Property | Description | Data Type |
| --- | --- | --- |
| Result | Outputs the Dynamic Formula Result. | Decimal |
