    Calculation problem


      I am trying to bring a calculation that works out the risk of Grass fires.


      The original equation is as follows:



      where B45 is Curing (how dry the grass is)

      B44 is Wind Speed

      B43 is Relative Humitity of the air

      and B42 is Temperature.


      The calculation I got was:


      2*Exp(-23.6+(5.01*Ln(Curing)+.001)+(.0281*Temperature)-.266*Sqrt(Relative Humidity+.633*Sqrt(Wind Speed)))


      The results are all wrong.  What is my mistake?
