# Media Capture - Common Properties

You'll find the following properties common to any controls that allow input of data:-

| Property | Description |
| --- | --- |
| Caption | This is the label or caption that appears on screen and is generally used to describe what to input, e.g. *Name*, *Enter Address* etc |
| Unique Name | You can think of this as the field name. By default, this is set to be the same as the **Caption**. If you're going to be using expressions however, it's often better set this manually. This is especially useful if you have a long caption name and also allows you to change the **Caption** without breaking any expressions that reference this field. For example, you may have a **Text Box** with the **Caption** *Enter customer name here*, in this case you may set the **Unique Name** to *CustomerName* which is obviously easier to reference. |
| Ready Only | If checked, then the field is read only and can only be used to display information. |
| Required | Determines if the current field requires some form of input before allowing the user to progress to the next page or save. Options are:-  <br>Yes (field is required)  <br>No (field is not required)  <br>Formula (An expression can be used to determine if this field is required) |
| Hidden | Used to hide or show both the contents of a field and its associated caption. Options are:-  <br>Yes (field is hidden)  <br>No (field is not hidden)  <br>Formula (An expression can be used to determine if this field is hidden) |
