    I say:
    
    Using excel 2000, this works!

    However, his other suggestion-
    
    "The Excel function "linest", lets you get at the coefficients from a
    regression and manipulate them in cells."
    doesn't look as if it will help, for me. The manual, and the help file, both
    tell me that LINEST is for fitting straight lines to data, whereas I need a
    polynomial (quadratic), fit. Which must be available, internally within
    Excel, in order for it to produce that quadratic trend line on a graph..
    
    I wonder whether this difficulty relates to the old version of Excel that
    I'm using (2000). Perhaps, later development has made that LINEST function
    more versatile.Or perhaps there's a different function, for fitting
    polynomials.
    
    Anyway, thanks to Dave's help, I'm now quite a lot further ahead.
    
    George.
