finding the highest result of a calculation with variables

[kman]

Hi,
I need some help in vba programing.
I have 10 variables located in cells a1..a10 that can have value of 0-20 with jumps of 0.1 (0, 0.1,0.2...19.9, 20)
in cell b1 I have calculated cell that is changing according to the variables.

I want to find which combination of the 10 variables will get me the highest calculated number in cell b1.

thanks for the help
