Custom Entity Types

Sometimes you'll want to create your own entity type when the built-in options do not fit with the user reply you are expecting.

You can find a number of other regular expressions to create your own entity types at

Here is the code used in the Code Step

errorMessage = 0;

// Extract zip code from a string
var zipRegexG = /[0-9]{5}(?:-[0-9]{4})?/g;

try {
    zipcode = zipcode.match(zipRegexG)[0];
  catch(e) {
    errorMessage = "Looks like it's not a zipcode" // or e.message;
