Is there a way to make the tab on an excel worksheet blink? I have a
multi-tab workbook that is opened every day. I want to blink a specific cell
if data exists in that tabs column A but not B.

Basically it's a task in column A and a completed in column B. I want to
blink the tab if the task is not completed so the person opening the workbook
will notice it and go to the tab. thanks.
