Calculated fields in ArcGIS Pro

AleemMohammed

Hi Everyone,

 

I am new to using ArcGIS Pro and Arcade, I wanted to have a few calculated fields in my table, not sure what's going wrong.  I wanted the user to choose a value for the CommonName field and the app would fill out the ScientificName field. So I tried using the Arcade syntax, this was what I came up with:

 

 

 

var commonName = $feature.CommonName;
var scientificName = "";

if (commonName == "Yellow Floating Heart") {
    scientificName = "Nymphoides peltate";
} else if (commonName == "Japanese Knotweed") {
    scientificName = "Reynoutria japonica";
} else if (commonName == "Invasive Phragmites") {
    scientificName = "Phragmites australis";
} else if (commonName == "Himalayan knotweed") {
    scientificName = "Koenigia polystachya";
} else if (commonName == "Giant knotweed") {
    scientificName = "Reynoutria sachalinensis";
} else if (commonName == "Fanwort") {
    scientificName = "Cabomba caroliniana";
} else if (commonName == "European frogbit") {
    scientificName = "Hydrocharis morsus-ranae";
} else if (commonName == "Dog-Strangling Vine") {
    scientificName = "Vincetoxicum rossicum";
} else if (commonName == "Bohemian knotweed") {
    scientificName = "Reynoutria ×bohemica";
} else if (commonName == "Black dog-strangling vine") {
    scientificName = "Vincetoxicum nigrum";
    return scientificName;
} else {
    // Default value if no match is found
    scientificName = "What";
}

return scientificName;

 

I know the script is reading the correct value for the CommonName because if I set the scientifiName to CommonName the value is filled in the field. However, my script is returning "What", do you know where I might have gone wrong with this?

 

Regards,

Thanks all for helping with this, I took another look at it and figured this code was way too simple to be giving this much trouble and I made a guess that the only other complication to this was that I was using a Domain. I was using the description of the code in the domain and that was the issue 😩. Once I switched "Yellow_Floating_Heart" for "Yellow Floating Heart" in the script: 

if (commonName == "Yellow_Floating_Heart") {
    scientificName = "Nymphoides peltate";

it worked as expected. I slipped up on that. Thanks everyone for helping with this.
