Just do colorList[0] or colorList.get(0)

[kahn-hubitat]

thats what i am doing.. there is no variable called colorList its colorList1.. colorList would be null

[tomw]

OK, whatever. But you're doing:

colorList1.get[0] Use parens with get() or just the bracket notation. Not both.

@tomw

colorList.get[0] Use parens

got ya parends instead of brackets.. thanks will givfe it a try.

I like to do this (with added null-safety check):

colorList1?.get(0) or colorMap1?.getAt("name")
