1) Obsidian has a value of 2 in the raws. When you check the item, it has a value of 6. Other stones have a value of 3. I wanted it to be worth less so my fortress wealth doesn't go up as quickly.
2 * [It_Made_of_Obsidian_Material_Multiplier_of_3] = 6.
In changing that 2 to a 6 you increased its value by a factor of 3, instead of decreasing it.
Does nobody understand English?
I did not change anything to 6.
The ONLY thing I did was change the value, in the raws, of obsidian from 3 to 2.
Then the raw rocks that are left behind from mining are worth 6 instead of 9. This is what I was trying to do. It worked fine.
However, on that particular game I was playing, mining the rocks out made my fortress value increase by 18 rather than 6. The value of the rocks, after the 3x obsidian bonus, was 6. I cannot make this any clearer without resorting to pictures.
THIS IS NOT GODDAMN ROCKET SCIENCE PEOPLE
