Traffic light system

Question

When selecting a number from a drop down menu is it possible to make a colour appear depending on what number is chosen. Like a traffic light system, you choose 1 and it comes up red, you choose 3 and it comes up green?
Thank you for taking a look

Well, you can use a slightly modified version of the script above. Something like this should do:
var risk = Number(this.getField("Risk").value);
if (risk>=1 && risk<=7) {
     event.value = "Low Risk";
     event.target.fillColor = color.green;    
} else if (risk>=8 && risk<=15) {
     event.value = "Medium Risk";
     event.target.fillColor = color.yellow;
} else if (risk>=16) {
     event.value = "High Risk";
     event.target.fillColor = color.red;    
} else {
    event.value = "";
    event.target.fillColor = color.white;    
This code should be used as the custom calculation script of the field where you want to display the "traffic light", and it assumes there's a field called "Risk" that contains the risk value (this field could be hidden).
Edit: fixed code
