Yep that's what I did - almost. Used relation for the child grid and parameterized view with the grandchild andpout a REQUERY in the AfterRowColumnChange method of the child grid.

>>Appreciate the fast come back. I took a look at your site and tried a few things but still can't get it to work. Again I have no problems using two tables especially when one of them is the initial selected alias but using three wheer the second parent is the child of the initial selected alias is defeating me. I have tried concatenated fields with and without alltrims and still can't seem to get anywhere. I suppose I could try an updatable parametrized view but I will probably try that last.
