Check if a specific tool is selected and set it to standby

var.temp0 evaluates to tools[0].active which points to an array containing elements (of I guess extruders) with the temperature for respective extruder (normally 0).

So if you write like this instead:

var temp0 = 0
if #tools[0].active != 0
   set var.temp0 = {tools[0].active[0]}
;end if

I don't know if that answers your question some?
