Arcade Expresssion

[FranHarvey2]

We have a field name:  valve service SDE.  The attributes are either "null" or a "url"  We have a working expression for the url to be returned.  We need an expression for when the attribute is "null"  return the text  "No Service Card"

Hey @FranHarvey2 

Here is a short arcade script that does just that if your feature is in this format:

var service = $feature.valve_service_SDE;

if (IsEmpty(service)) {
    return "No Service Card";
} else {
    return service;
}

Hope that helps!

There's also DefaultValue, which was made for this very thing. If there's a value, it returns, otherwise it falls back to the value you specify.
