# Create Dynamic Variable This is a pre-built Action located under the **@Generic Element.** The functionality of this Action in Avo Assure is to create a dynamic variable, assign a value based on the input provided. The execution result is stored in the given dynamic variable. ## **Syntax** **Input Value**: `;` {% hint style="info" %} **Note**: * The variable you create appears within curly brackets {}. * A dynamic variable does not have a fixed value, and you can update it at any point during test execution using the **Modify Variable Value** action. To learn more about how to modify, [click here](/avo-assure/actions/generic/variable-operations/modify-variable-value.md). * The index starts at 0. * When you create a dynamic variable in a Test Step Group, you can use its value in any Test Case or Test Step Group within the same project. * You can access and reuse the created dynamic variable while building an end-to-end flow within the same project. {% endhint %} | Argument | Description | | --------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | |

\

(Required)

| Provide the name of the variable you want to create. | |

\

(Required)

|

Provide the value that you want to store in the variable.
Supported strings are:

| **Output Value**: `(Optional);(Optional)` | Argument | Description | | ----------------------------------------------------------- | ----------------------------------------------------------------- | | \(Optional);\(Optional) | Both dynamic variables store the status as **True** or **False**. | ### **Example 1: Creating a Dynamic Variable with a Specific Value** In this example, we explain how to create a dynamic variable and assign a value at runtime. * **Action**: Create Dynamic Variable * **Input Value**: {Username};Admin * The first argument (**{Username}**) specifies the name of the dynamic variable. * The second argument (**Admin**) specifies the value of the dynamic variable. * **Output Value**: {VariableStatus} * The execution status is stored in this **{VariableStatus}** dynamic variable with the following possible values: * **True**: If the variable is created successfully and the value is assigned. * **False**: If the operation fails due to an invalid variable name or missing value. {% hint style="info" %} **Note**: If you do not define an output variable, Avo Assure displays the result only in the execution logs and does not store it in any variable. {% endhint %} * **Logical Explanation**: The **Create Dynamic Variable** action fetches the value from the **Input Value** column (**{Username};Admin**). It creates a dynamic variable named {Username} and assigns the value (Admin) to it. This variable can be reused throughout the Test Case. The execution result is stored as (True) in the **{VariableStatus}** dynamic variable.
### **Example 2:** Creating a Dynamic Variable Containing an Array and Accessing Its Values In this example, we explain how to create a dynamic variable that stores an array and then retrieve a specific value from that array using its index. * **Action**: Create Dynamic Variable * **Input Value**: {Values};\[12,34,23,45] * The first argument (**{Values}**) specifies the name of the dynamic variable. * The second argument (**\[12,34,23,45]**) specifies the array value of the dynamic variable. * **Output Value**: * The execution status is stored in this **{VariableStatus}** dynamic variable with the following possible values: * **True**: If the array variable is created successfully. * **False**: If the operation fails due to an invalid variable name or incorrect array index. {% hint style="info" %} **Note**: If you do not define an output variable, Avo Assure displays the result only in the execution logs (Avo Assure Client) and does not store it in any variable. {% endhint %} * **Using Array Index**: * When the action creates the array, you access its values using index value as shown below. * **{Values\[0]}** → stores **12** * **{Values\[1]}** → stores **34** * **{Values\[2]}** → stores **23** * **{Values\[3]}** → stores **45** * **Logical Explanation**: The **Create Dynamic Variable** action takes the value from the **Input Value** column (**{Values};\[12,34,23,45]**) and creates a dynamic variable named {Values} containing the array \[12,34,23,45]. Each position in the array can be accessed using array indexing. The **Display Variable Value** action displays the value at the 2nd index of the dynamic variable by using **{Values\[2]}** as input and shows the value as (23).
