i get this. * Invalid parameters: $iif while using this.
Code:
  
on *:dialog:cpanel:sclick:19: { $iif($did(16).state,services sop $chan($active) add $did(14,text),$iif($did17).state,services aop $chan($active) add $did(14,text),$iif($did(18).state,services vop $chan($active) add $did(14,text)))) }

I am probably just over looking something, but it is good to have other people to ask when you arnt quite sure.
