labeling in Arcade

IngridAnneessens — Mon, 04 Sep 2023 09:11:48 GMT

I want to label my feature as follows:

when ADRESSTATUS = Gehistoreeerd -> No label
when BUSNUMMER = Null --> Huinummer
When BUSNUMMER is not NULL --> Huisnumer underlined

I keep getting an 'invalid expression'
Can anyone see what's wrong here? Is there a beter way tot do this?

You are missing a ')' at the end of line 5.

I don't see where I have to put it:
if (!IsEmpty(Busnummer)) {return + Huisnummer};

tl;dr:

return When( Adresstatus == "Gehistoreerd", null, IsEmpty(Busnummer), Huisnummer, !IsEmpty(Busnummer), `<UND>${Huisnummer}</UND>`, "Default value" )

A few pointers:

return + something is not valid syntax. return something is. More info on return.
= is for assignment (this variable now has this value), == is for comparison (does this variable have this value?) More info on operators.
You can append multiple string values (what you tried with the <u>), but you have to actually make them strings using quotation marks, and you have to either add them ("<UND>" + Huisnummer + "</UND>") or use template literals, which I did above.
Label formatting tags are not the same as HTML tags.
For chained if-then blocks, you can use the When function.
