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. To unlink a prompt, switch to the prompt linking mode. Click on the field you want to unlink, drag to an unused area of the window, and release the mouse button. The prompt will be unlinked.
