Hi Dale,

Thanks for that. I've added the Group column in the "Resource Sheet" and grouped the resource. This transfers through to the Gant Chart when the "group column" is added. The next step is to add a custom filter with text in the value's field that call up the drop down when the filter is run. With the "show related summary tasks" tick box selected, the result is all of the task for that group. I had the filter sorted many years ago but I can't remember what the text in the Values group has to be.
