who can help me?

I want to add a option name Thickness value 0.8mm




when customer choose 0.8mm the price= original price*1.6

how to set up it? I just can use + or - but not *





thank you.

Can insert the actual price increment
But if will always be *1.6 use the factor & offset

factor = 1.6
offset = 1.0
