I'm having trouble writing a rule to change the color of the "@" symbol to black while keeping the rest of the email address red. When I validate the rule it returns my field correctly but it is not changing the color when I preview it. I have checked and I labeled the color exactly how it is spelt in my loaded colors and I have "treat returned strings as tagged text" selected. What am I missing? Thanks!
return Field("Email").replace(/@/g, '<color name="Black">@</color>');
