I have a risk register and want a field to automatically calculate the risk rating based on consequence and likelihood. If you are able to provide examples on how to do this I can build in our risk rating matrix into the code. Thanks 
For example:
Field 1 (Consequence) = "Moderate"
Field 2 (Likelihood) = "Possible"
Field 3 (Risk Rating) to specify based on Field 1 & 2. In this case "Medium 5"
