# Data types for checkmarks

> Define the values a checkmark field returns when selected or cleared — Yes/No, 1/0, checkmark name, or custom values — on the Data tab in FlexiCapture.

The data type for checkmarks can be set on the Data tab of the field properties dialog box.

The data type for checkmarks determines the values to be assigned to the checkmark field for a selected and unselected checkmark. The corresponding value will be contained in the export results and in the **Value** property of the [ICheckmarkValue](/flexi-capture/appendix/scripts/icheckmarkvalue) interface.

Select the appropriate options for checkmark values:

* Yes / No if the checkmark has been selected, the field value is "Yes", if unselected "No".
* 1 / 0 if the checkmark has been selected, the field value is 1, if unselected 0.
* \<Checkmark name> / Empty if the checkmark is selected, the field value will match the checkmark name, if unselected the field will be assigned an empty value.
* Custom by enabling this option you can enter your custom values, Selected for a selected checkmark, Not selected for an unselected checkmark.
