Fixing Errors |
If your worksheet contains several expressions with errors, find the expression flagged in red nearest the top of the worksheet, and click on it to see the error message. If you are still unsure what caused the error, press [Shift] [F1] on the error for an explanation of the error message.
If a user-defined function is marked with an error, check the function definition, or its type signature, to find the actual source of the error.
Often, the cause of an error is not in the expression issuing the error, but in a previous expression. Error-tracing may help you find the cause.
After you fix the error, recompute the expression.
