When you enter invalid data into a field, the data is displayed in a specific color. You
can choose which color is used.
Invalid data might be an identity that is already in use on the chart. Other invalid data
might be a textual character in a numerical field, or a numerical value that is too large or too
small. To move the cursor to a different field, or save the data or setting, you must correct the
invalidity.
To change the color that invalid data is displayed in, select a color from the Error
Text Color list.
