Thanx Sarah,

I will try it out as soon as i get back home.

/Niklas

I would like to use this as an calculated parameter "CO2 = 12.839 * dKH * 10^(6.37 - pH)" or as i try to use it with Picolog "12.839 * B * 10 ^ (6.37 - A)" but the ^ are causing me some headache, its not working as ^ and i cant find a function to replace it with either.

The problem is solved, some running software caused the problem.

Sorry for the nag.
