My question is how to Make this flash.. blink etc ??? bottomline is
how or
is it possible to flash back such error with some effect that alerts
instantly . Like in online EXAM or poll or survey etc. How to do so
in EXCEL.

I don't mean animatioin, in the scenerio above gave result "Revise
Your Diet"
(EXAMPLE)which is an error I want to make it auto with extra alert
function
so any suggession?

Excel provides *NO* built-in means of *CHANGING* any format
characteristic
automatically at any frequency. That means 'flashing' would be changing
cell background (interior) and text colors between two (or more?)
different
states at a frequency like once or twice per second. You could only do
that
with VBA code, and the result would noticeably degrade Excel's
performance.

If your absolutely certain you want to do this, then search the Google
Groups
archive for past threads containing the word 'flashing'.
