Arcade for Webmap - When Function Weirdness

Hi all,

I've got stuck and I can't work out why. My workflow is as follows - a user in the field captures some data and I want to use Arcade to classify that data to create improved visuals. I've written a When statement which appears to be working in the sandpit but once it goes to the map, the value fails to materialise....

appears to work, but...

Nothing appears in the popup? I should be getting a VL at the very least.

// Calculate the width category var width_cat = when( $feature.WIDTH<=0.5,'VN', $feature.WIDTH<=1,'N', $feature.WIDTH<=2,'M', 'W') // Extract Oil Distribution to make following coding easier var oilDist = $feature["OIL_DIST"] // Calculate the Initial Ranking var ranking = when( oilDist=='SP'&&width=='M','L', oilDist=='SP'&&width=='W','L', oilDist=='PT'&&width=='N','L', oilDist=='PT'&&width=='M','M', oilDist=='PT'&&width=='W','M', oilDist=='BR'&&width=='VN','L', oilDist=='BR'&&width=='N','M', oilDist=='BR'&&width=='W','H', oilDist=='CN'&&width=='VN','L', oilDist=='CN'&&width=='N','M', oilDist=='CN'&&width=='M','H', oilDist=='CN'&&width=='W','H', 'VL') Console('Width',$feature.WIDTH,'width_cat: ', width_cat,'oilDist: ', oilDist) return ranking

Anyone any ideas? Do you get the same?

Your variable is named width_cat, but you're using width in the When() function.

Well now I feel stupid... Thanks @JohannesLindner

Ha, that's no reason to feel stupid! I've misnamed or misspelled variables so often that it's one of the first things I look for, now...
