Under fitting function organizer, I click add new function and put in the 2 parameters a, b. When I hit simulate, nothing shows up on the graph. Not sure where I'm making a mistake. Also, on a side note... I want to calculate the average values of a new numbers in a column so I typed in the following formula under Set column values, however it does not give me any values in the column, not sure what the error is in my formula...Col(A)/(average(Col(A)[6],Col(A)1[12])) Thanks, [/quote]   Check here to include your profile signature.
