Hi Domenic,

Thank you very much - that worked Great.

I used this as the Conditional Formatting Formula Is:
=IF((ROWS(I$19:I19)<=ROWS(Position))*(MOD(ROW()-ROW(I$19)+0,3)=0),3,"")

Thanks
Sam

Assuming that Column I is the column next to your dynamic range, try the
following...

Conditional Formatting:
a) Select cell I19
b) Format Conditional Formatting Formula Is
c) Enter the following formula:
=(ROWS(I$19:I19)<=ROWS(Position))*(MOD(ROW()-ROW(I$19)+0,3)=0)

*Note that every 3rd cell will be highlighted, starting with the first
cell. If you wish to start with the first occurrence of 3rd, change +0
to +1.

d) Choose your formatting
e) Click Ok
f) Copy the formatting to other cells in the Column using the 'Format
Painter' or 'Copy Paste Special Formats'

Formula:
I19, copied down:
=IF((ROWS(I$19:I19)<=ROWS(Position))*(MOD(ROW()-ROW(I$19)+0,3)=0),3,"")

Hope this helps!
