# NE

> The NE function compares two values to check whether they are not equal. It is supported in YiDA Form and workflow design scenarios. Use this function to check whether the requested quantity differs from the stock quantity and block form submission accordingly.

The **NE** function compares two values to check whether they are not equal. If they are not equal, it returns true.

## Supported Product Scenarios

The NE function is supported in the following YiDA scenarios:

* Form (main table fields)
* Form (business association rules)
* Form (validation)
* Workflow design (validation rules)
* Workflow design (association actions)

## Syntax

```text theme={"theme":{"light":"github-light","dark":"github-dark"}}
NE(value1,value2)
```

## Attribute Description

<table>
  <tr>
    <td>**Attribute**</td>
    <td>**Required**</td>
    <td>**Description**</td>
  </tr>

  <tr>
    <td>value1</td>
    <td>Yes</td>
    <td rowSpan={2}>The values to compare. Numerical, Text, Date, and other components are supported.</td>
  </tr>

  <tr>
    <td>value2</td>
