Price per meter

[neutrino86]

Hi,

I make a website where I will sell cut out aluminium bars.
I added a customfields for length and now I try to vary the price according to this parameter, I can't find a solution, it is possible to create a specific rule of calculation?

Thanks,

Maybe, if you put price for 1m and then the buyer can select 2,3,4...N meters?
Or you need 1,5m or 1,23m?

unfortunately not, I need a value close to 0.1 mm from 5cm to 120cm ...
