Thanks Nadya,

that got my brain going. I got what I wanted with this:

iif(inlist(mod(recno(),8) 1, 2, 3, 4), GreenColor, RedColor)

>>Hi,

>>I have a grid which is displaying information like this:
>>

>>Age   5yrs   10yrs   20yrs
>>50    1235   1345   7676576
>>50    3234   54365  658678
>>50    87668  87699  768898
>>50    76576  65767  09809
>>55    876987 090980 09809
>>55    765876 989878 768767
>>55    876876 785457 6757687
>>55    654655 435354 6546565
>>60...
>>

>>and so on, in groups of 4 records per each age.
>>
>>I want to highlight alternating groups to make it easier to read. What formula can i use to do this?

>>Thanks.
