// Name of form that uses this function must be 'form1'
// possible variable to pass for createMenus() and updateMenus() is 'bacOnly'.
// bacOnly value can be any value - i've been using '1'. 
// the function checks to see if bacOnly is defined - if it is, only baccalaureate programs will display.
// this allows you to just use the 'program' select menu in a form to display baccalaureate programs.
