You can define inputs of commonly used Glide Virtual Agent
(com.glide.cs.chatbot) data types in Assistant Designer without writing a
script. Define the input data type on the Start node of a custom control or topic
block.

## Data types in Assistant Designer {#va-data-types__section_zsz_x43_bpb}

The data type designation allows Virtual Agent to perform secondary
validation on NLU predicted values. For example, if your choice list has red, white, and
blue, but the NLU prediction service returns green, the input won't be slot-filled because
that wasn't a valid choice.

When you specify an input with a data type on a calling topic, you can use the data pill
picker to specify information collected from the user or previously looked up in a custom
control or topic block.  
{#va-data-types__table_w53_vk3_bpb__entry__2}

| Data type | Description |
|-|-|
| String | Alphanumeric text. The value uses JavaScript data conventions. |
| Boolean | Boolean value of true or false (yes or no). |
| Reference | Table record by sys_id. Select a ServiceNow table in the Table field. You can define conditions for the returned record. |
| Date/Time | Date and time values. |
| Array.String | Sequence of alphanumeric text values. To limit the number of strings that authors can specify, use the Max Number of Rows field. |
| Array.Datetime | Sequence of date and time values. To limit the number of dates that authors can specify, use the Max Number of Rows field. Click + to specify more than one default value. |
| Array.Reference | Sequence of table records by sys_id. Select a ServiceNow table in the Table field. You can define conditions for the returned record. To limit the number of records that authors can specify, use the Max Number of Rows field. Nota: The Array.Reference input data type in Virtual Agent Designer corresponds to the List.\[Table\] input data type in Workflow Studio. For more information, see [Action input and output data types](https://www.servicenow.com/docs/access?context=action-inputs-outputs&version=australia&pubname=australia-build-workflows&ft:locale=en-US). |
| Array.Choice | Sequence of choice list values for a specific choice field. For example, printer, computer, and monitor. |

Nota:  
Duplicate default values are not allowed with array data types.

## Example data type definition {#va-data-types__section_zhz_kp3_bpb}

This User Name Array.Reference input variable limits the number of records to 5. It
references the sys_user table with the condition that all names must start with
a.
