Ok, here is a sample of the data i have:

Component No Interval(hr)
Labour Hours
Electrical Management System 1 250 2
Engine Repairs 1 250 2
Exhaust Pipe 1 250 1.5
Fan Drive 1 38000 16
Final Drive Pump 1 15000 3
Fire Supression 1 9000 5
Flush Radiator 1 9500 3
Frame 1 250 2
Fuel System 1 9500 12


What I want to create is like a history, eg between the interval of 0
to 1000hrs there is "x" labour hours required. this need to go out for
45,000hrs, so these events reoccur.

can anyone think of a way to set this out efficently?

Thanks
