Using When is fine, but you need a final "default value" that the function will return if none of the conditions are met.

var icon = When( condition1, 'this', condition2, 'that', condition3, 'the other', 'something else' )

Iif is for true/false situations, and can only return one of two values.

There's also Decode, which takes an input value and compares it against a list of other values, similar to what you're doing here. As with When, you need a final default value.

var icon = Decode( s, '#00ff00', 'green', '#ff0000', 'red', '#ffff00', 'yellow', 'something else' )
