Highlight Dynamic Rows

Hi All,

I have an issue where I need to highlight all columns which have a SAT or SUN as date.

I can do that ok, but if I insert a new row for another product everything is out of whack due to hard coding.

But I don;t know where to start to address this issue.

Can anybody steer me in the correct direction.

I have attached a workbook as to what I have done so far.

Thanks

Lionel
