Maybe you'll like this. In another cell, say Z1, put
=IF(A1=A2,"WARNING!!","") and hide column Z.
Insert a Textbox near A3, select the border. While the textbox is selected,
click in the formula bar and enter =Z1. Format its font as 28-pt, Red, Bold,
format the textbox itself as no fill, no border.
Now when A1=A2 you'll see the big bold warning and when they're different
you'll see nothing.

Use conditional formatting to highlight the cell.

Can anyone help with this:

How can I make a cell to flash a text, let's say "Warning!" whenever a
condition is met. For example, if cell A1 = cell A2, make cell A3
flash the text "Warning!".

Thanks,

Amir

Yes, I want something bolder than just conditional formatting. Indeed,
it is to provide a better alert.
