I did not make myelf clear. here is a sample of the actual data

What I want to do is group by alternating colors based on the account
number. The SIDS are unique and not necessarily consecutive, in this example
there is no acct# 2. In the above example all SID 1 is green, the next SID,3
in this case would be green and forth.
Conditional is problematic, since the SIDs are not consecutive, this would
give the effect of odd/even. In this case SIDs both SIDs 1& 3 above would be
green using the MOD argument.

Is this a little more clear?
Thanks
