oh my bad, the substring with a is out of the loop while a is only defined in the context of the iterate; you can't use it outside.
do a :
let string : String = Sequence{thisModule.NewEventRefines(Sequence{'(' +(self.GetSupplier((self.GetClientNiveau(goal))->flatten())- >flatten())->iterate(m; a: String=''|
a+('Ev'+m.name +' ||| ')) in
string.substring(1,string.size()-3)+')'+' Refines '+ 'Ev'+(self.GetClient(goal))->flatten().first().name})}
