Question : How do I calculate software availability in an Excel spreadsheet?

On the attached spreadsheet, I'd like to be able to calculate the daily availability/uptime for some software.  I have been able to calculate the outages in minutes (F3) based on the time values in A3, B3, C3, D3.  What I am having a problem with is calculating the percentage of availability(downtime/uptime) for that day.  Since F3 is set as a custom [mm] format, I am having an issue with this calculation.  Could someone out there help me out?  I've attached the spreadsheet which should show what I've done thus far.  Thanks!
