I am using Project 2007 and I have made a value list via lookup and want to know how am I able to allow multiple selection of this list. For instance, I got a field called 'systems' and I want to select one or more of the systems in the lookup list. With the lookup fucntion, it will only allow 1 selection. So, is using the lookup function correct in this case or is there any other way I can do this? Thanks.
