FR - Need to add row shading on every Nth row

Question

My client has a report where they want to add shading to the rows on every Nth row. The rows have member selections such as Children of or Descendents of, so there are varying number of report rows produced.
I've played with using a formula column and using the Rank and Mod functions to rank the sorted column and on every 3rd row (when Mod 3 = 0) have the shading applied, when it is not 0 no shading. This works to a point and this is where I am stuck. When values in the rank are the same, the shading skips such as if the value in the sorted column is missing or zero.
Any other thoughts???

Hi Rob
It sounds like you are really close, that is probably the way I would attempt it. Have a look in the user guide at the rank function syntax and I'm pretty certain there is are optional fields so that non-numeric values (e.g. #Missing) are given a rank and a keyword that tells HFR whether you want all records to have unique ranks, syntax is something like:
Rank([A,1:10].ifNN(-1), descending, true)
Where the ifNN(-1) tells HFR to assign a value of -1 to all non-numeric values and the true at the end tells it you wany unique ranks.
Hope this helps
