HELP - Total Float While Levelling

Hi All,

I have a resource loaded and linked schedule with a finish milestone (forecast) linked to a constrained mandatory finish milestone(target finish date) and can see my float correctly in the Total Float column with no resource constraints applied. When i add resource levels to the schedule, it naturally extends the finish dates as i expected. My forecast finish milestone goes beyond my constrained mandatory finish milestone however my total float column has not changed and still shows a positive float! It has not calculated the REAL total float with resource levelling.

Any help on this would be massively appricated!

Cheers,

Hayden
