Use a formula to translate % complete into days complete:
=(EndDate - StartDate) * % Complete
DaysLeft:
=EndDate - DaysComplete

ok so there are loads of Gantt charts out there that use days completed
and
days left and only a start date....I would like to use % completed and
remaing using an end date - does anyone know how to do this?

Task description

% completed
% remaining.
