This is my first attempt at this and I'm getting syntax errors. What I want is a column that has a conditional value based on another column "Probability".

I have tried a few variations with assistance from other question answers but cannot get it to work:


High is 1, Low is 0.3, Med-High is 0.8 and Med-Low is 0.6

Keep getting "The formula contains a syntax error or is not supported" Can anyone help or recommend a site where I can learn how to do this?
