Trying to write an IF formula for use in Arcade Expressions in model builder

[AndrewReynoldsDevon]

I'm using the calculate field tool in model builder & need to use an IF formula in the expressions box.

So far the code looks like this which doesn't work

if (RouteType) = 'Parental Assistance'; 
Return $feature.ParentalAllowanceMiles;
Else return
$feature.RouteOutwardDistance + $feature.RouteInwardDistance

I need the Field Daily Mileage to recognise if the record has the Route Type of 'Parental Assistance' & then return a the value in that field so no calculation required. But for every other 'Route Type' the original calculation of adding 2 fields together needs to remain.

[JohannesLindner · Accepted solution]

if($feature.RouteType == 'Parental Assistance') { 
    return $feature.ParentalAllowanceMiles
}
return $feature.RouteOutwardDistance + $feature.RouteInwardDistance
