Conditional Formatting - color groups based on row value

[djangeroo]

Hi,
I am new to the forum and impressed by the great advise that's out there.

This is my problem:
A list with numbers in column A, these numbers can be used over multiple rows, sometimes 3, 5 or more/less.
Every time this number changes, the color for the entire row should flip between yellow and no color.
Sequence of the number in column A is not always odd / even. I tried various suggestions regarding this topic but I do not get it straight.

Thanks for your help.

OK, I was really confused, forgot to remove a background color I previously and manually applied... Now everything works fine, thank you.
