	I have built a report that returns child data(c) where the string values can be one of 1,2,3,5,8. I would like to filter the selection down to just the parents whose child values are either 2 or 8 only, meaning that the parents only have child data that are 2 and/or 8.

	if you are looking for a crystal only solution (meaning you do not want to use stored proc or its equivalent) you can use group select expert to achieve this. group on the parent record create a 'flag' formula field to convert the values in the child records into a useable function. //flag if field in ['2','8'] then 0 else 1 now you can insert a maximum of the flag field at the group level maximum(@flag,group) any group that has a mx=0 meets your criteria so you can use that int eh select expert (set to group) maximum(@flag,group)=0

	Thanks DBlank, I think that is going to be the solution for me.
