Help with Record Selection Formula

I have this:

{TimeRecord.OwnedBy} = ({UserInfo.FullName}, {?AS Team}) and
{@Date Resolved} in {@StartDateMD} to {?End Date}

I need to be able to Have the userinfo.Fullname populated based on the AS Team criteria. (AS Team = manager name that is selected by the user) So I need to select the manager and then the employees under go into the report.

Suggestions?
