I want the column called "Submerged_weight" to show the calculated value on a IDW automatically. I`d rather not extract it to excel etc. as it will then be manual labour to get it correct value on the idw later.
But The custom value is a good start. How do i get it to give me the value of the expression, and not just showing me the expression? (I get: 1000-(500*1.025) instead of 487,5)
