Sorry, I have just one more question. Normally I clear variables before assigning values so no mistakes are made. But the Use Unset Overbar[p] only works when Overbar[p] has assigned a value otherwise you will get an error/warning. Is there a way to avoid this, like asking if a variable is already assigned a value.
