You can link a field to the text prompt associated with it by using the Link Prompt item in the Tools menu. By linking a field to its prompt, the prompt can indicate the status of the field, such as if the field is disabled or required.
To link a field to a prompt, choose Link Prompt from the Tools menu. Click on the field and drag the mouse pointer to its prompt (the text describing the field). A flashing black line will indicate that the link was made. Linking a prompt is shown in the following illustration.
When you’ve finished, be sure to choose Link Prompt again to turn prompt linking off.
