Hi All,

I'm trying to do something which is probably painfully simple but I haven't been able to find the syntax anywhere. All I need is to use the forecast function =FORECAST(I902,F832:F901,I832:I901) but want to substitute a hard coded from and to value list, such as something like =forecast(71,F832:f901,{1-70})

That is, forecast case 71 given a range of 1 through 70. What is the correct syntax to give a from and to value? Curly brackets don't seem to work, and I don't want to do a list like {1,2,3,4,5,6,7...} which would be a pain.

Any ideas?

Thanks in advance for your help on this,
