So this is probably something that should be very simple, but it's giving me
a headache.
I use excel at my job to keep track of stuff that needs to be picked up. The
value of this cell is manually inputted whenever it changes, Excel doesn't
calculate the value in any way. If there's 2, I input two. If it's 0, I put
in 0.
What I want it to do is blink if the value I input is greater than 0.
All the codes I've found only work if the cell value is being calculated by
Excel, or it effects more than just this particular cell.

The cell used is J1.
I want the color of the background to remain the same grey color, and if
it's 0 the text is a light grey, if it's 1 or greater the text blinks between
grey and bright red.

Can anyone help me?
